The only thing I didn't like is your comment about not checking the fuse first. That's task one with all electrical. I resolved my problem by removing the wire from the factory plug (cut it off) and attached to the positive on the battery. Runs like a champ now.

Wow, this was awesome. I have a 1995 chevy astro van. I am looking at my vehicle when I see this. Same issues for me. I have replaced my electric fuel pump twice. My previous mechanic stopped charging me when I had this issue of cranking but not starting. He would fix it. He also installed a battery switch because my battery kept draining. The wires are so old. Anyway, my new mechanic, the old mechanic's friend, is maybe new to this. He thinks it is the fuel pump. Maybe it is but maybe it is this thing behind the battery. I see it there and I see the other things on the left side. This video really shows me what is happening. Sorry to say I have no background in electrical stuff or I would attempt to fix this thing myself. That area behind the battery sure looks worn. I was planning on selling this back to the county who wants to get these old vehicles off the road. I know this van will run for 300k. It now has 155k. The exhaust it puts out sucks. It is rickety on the freeway and the AC leaks. And the windows don't work. Other than that, it is great. Thanks again for this video. Cool to see how things work in there. Another question I have is: Is there any way to decrease the exhaust on this vehicle? It does put out a lot of pollution.

Great video. I do prefer using a power probe, personally for a couple of reasons. Mainly because a test light might show that there is no voltage by not lighting up at all but if it does light up it tells you that there is voltage but doesn't tell you how much. Also, I like the power probe because I can send full battery voltage to a load ground to check ground integrity. If the circuit breaker trips in the power probe, the circuit can handle current. The power probe 3 has a display which shows voltage which is great. A test light has it's place and is useful but the power probe offers much more information to me when diagnosing. I feel it makes me more accurate and faster which is always my goal.

Thanks alot for this video. My 92 S10 2.5L had a ground issue from me replacing the Blown OEM speakers with the same size 9x4 and 6x4 4-WAY replacement speakers. According to my friend, he said that the Chevy electrical system keeps a circuit through the speakers even when the key is out of the ignition. My battery would be exhausted within an hour or so of being shut off. Anyways when I got back to the truck and disconnected the speakers, the fuel pump wasn't supplying fuel to the TBI, no matter what. I had seen the pt 261 or 12101870 connector at the back of the motor dangling without a cause. Sure enough following your lead, hooking that up to the to the positive, I struck smelly gold. I know there is a burnt front driver side speaker connector, where it must have shorted. That's the only thing I have spotted as of yet. I hope to find a fuse blown. I am not sure, I left the radio out, and unhooked the speakers. That might be the fuel pump problem for me. I'm going to have to dig deeper. You're video is the only thing on the net that described the PT 261 connector, and what it does. Thanks again.

Dan here is an update still trying to fix my expy. Expy failed going up hill on short out of town trip. replaced fuel filter that was clogged.. ran perfect for 3 days. It failed after errands in a parking lot.. went to get it.. i drove it home.. for 2 days cranked perfect.. continued to run gas out over the next few days so the fuel pump would be easier to change. It failed to start again for five days. Researched . I have Chilton's ECT. There is a limited amount of info in them. I am an ex electronic tech. Understand relays ECT. So watched videos ECT. Checked Schrader valve had gas there. I decided to turn the engine over.. it started (we are dealing with an intermittent here) I took it to a neighbor and he put a bid tool on it.. not a cheap one.. it initially said misfire on cylinder 4.. that made sense because when it quit, it did misfire going up hills I told him to clear the memory.. He found no codes..no cam sensor problems, no crankshaft sensor problems, always has had the sound of prime, never checked voltage at fuel pump relay or pump itself. I hesitate to pup 12 volts to fuel pump willy nilly, as it may feed back and destroy electronic infrastructure. I know this can be the inertia switch (they sometimes are intermittent). It could be an insulation leak to the chassis. I don't know if I am getting spark.. it seems like like the obd tester would catch that.. The problem is that it is intermittent. I notice this doesn't have the normal spark plug wire setup and I think this is cop setup. I am a little confused how to properly check for spark do I use a noid. Oh yes it is only showing about 30 psi on idle and 35 on acceleration maybe a little higher at high rpms. Also my fuse board under the hood and below the steering wheel does allow pull and replace of relays. If it comes down to it I can fix boards, but if it's a expensive chip.. that probably won't be happening.. I suspect we are dealing with an obvious component. If any body can give me a detailed description of how this all works please do so.

Why in the infinite wisdom of the modern world would you make circuits where a fault in headlights or CIGARETTE LIGHTER! (?) would disable the computer/fuel pump and the whole damn car?!!! Hell - use two separate batteries/or computers in every car if needed! Why don't we live in a world where the designer figures a sytem where you may not have lights (or a light for a smoke) but at least you wont be stuck on the side of the road?!!! Chasing electrical problems didn't have to be the drag it is car makers - this guy is a competent, trained mechanic but even he has trouble finding out how the main ecm gets power/what is on ecm fuse without a diagram. Should be well labeled at fuses etc.

Very simple to put a list or easy to follow diagram in owners manual or on fuse panel as to what runs on each fuse for lay people or a roadside repair - and they usually don't. So as a mechanic - do you think it's smart design when a fault in a headlight connector disables the whole vehicle? Same with dome lights/lighter/accessories. There should be a whole other computer and battery operating these that has nothing to do with starting the car. Common sense - and nobody stranded.

I was just looking for the fuel pump test lead location to see if I could use the fuel pump to drain fuel from a tank that has held this fuel from back since this video and got caught up watching the whole video. This 94 S10 pickup has a mint body, interior, new tires but threw a rod on #1 cyl. Could not find one of these early vortecs so I took the bottom end from a '99, used the '94 top end and TBI intake. Had to modify the oil pan on the '99 so the slave could bolt on. The '94 came with a metal timing chain cover that took 2 extra mounting bolts then the newer block so I welded them closed. Runs but 4+ year old gas and has to go so I know what I'm burning. Anyway, great diagnostic class vid here. Thanks. Oh, I have a Modis Edge with the 19.4 update. The code it brought up was a 228. OBD 1 has 2 digit codes. Called Snap On, they couldn't say why and said to run it under a Sonoma. Finally got the 2 digit code running as a Jimmy.

I used the load pro and pulsing that end terminal (Dark green & white wire at the fuse box connector) and it drops considerably, almost 0, does this mean there is a short or weak wire? Also, when pulsing it, the AC fuse clicks. I removed it and nothing changed.

aul was a good case I heard you say that you could not hear the injectors because they are under the intake manifold We use a stethoscope I work at the AA in Holland so often been the fast road where much noise is hope to have made a small contribution

@ScannerDanner If my car temporarily starts when I spray starter fluid into the throttle body, is that an indication that the ECM is functioning? My car only cranks, no start. 2005 Jaguar Stype v6

+Harley Rider it depends on the ignition design. For example, the one on this vehicle does not need the ECM for spark control while cranking. I could literally unplug the ECM and spray starting fluid in the intake and it would run (until the starting fluid ran out). So all you know right now is you have spark. My suspicion is the ECM is controlling spark all the time on your jaguar. So yes, this at least tells you the ECM is "alive". In this video is a playlist that involves about 20 other videos I've done on fuel pressure testing. You need to check your fuel psi and then injector pulse next

ScannerDanner You mention to test fuel pressure, but I have non because there is no power going to the fuel pump, Not sue if the lack of power to the fuel pump would also mess with the injector pulse test.

wish you could fix the mess i have going on. I swapped motors from v6 fuel injection to v8 carburator . I'm trying to get my fuel pump to run correctly with out the fuel injection wireing harness. I need to know what needle prongs do I have to jump in the existing wiring harness to complete a circuit for fuel relay to operate correctly. ECM, PCM , RPM. crank shaft sensor or what? Help please!!

Goodness looks like I may have the same problem with my 92 Chevy Astro. I cant hear a click or anything at the fuel pump relay. For a sec I thought I had ran out of gas. When I try to turn it over there is no gas coming from the injectors. I don't have a fuel pressure gauge. And I will try to probe the relay tomorrow as well as the power distribution plug to see if its getting power. Mine was melted to hell too and someone has already worked on it before. The strange part is that it was working just fine before but recently just died at idle and won't really start back up. Guess I'd better check the fuses too.
