Get the compression gauge in each plug hole. And watch for bubbles in coolant while cranking for head gasket check

I had a very similar problem with my 89. It ended up being the distributor. The pick up coil/hall sensor (PIP) failed. I’d hate to send you down a rabbit hole and have it not be that and worst and most frustrating thing to do is throw parts at it but, I paid like $65 bucks for a brand new distributor with the ignition module already installed. Also, if you do end up doing that, when finding TDC make sure your balancer hasn’t slipped and timing marks are correct . Initial timing should be at •10 degrees TDC.

Also, there is what’s called a spout connector that needs to be unplugged before you adjust timing. I actually was able to advance timing slightly by just 12 or 13 degrees before I had any spark knock or problems. Results may vary.

I had a similar issue on my 86. I ended up renting a noid light set to test my injectors. Found the loom had rubbed through under the intake plenum, and my injectors were grounding out.

I have a 89 and it sat thru hurricane ian and from what i learned the computers corrode so check the caps on the motherboard its under the dash in the kick panel with the hoodlatch and then i had to do ths fuel regulator i had to cut all the vacuum and replaced it with 3/8s hose from hoke depot i did the fuel pumps and i say pumps because you have a low and high pressure pump on these also the fuel regulators get extremely dirty and clogged you should get the little black can on the fuel rail under the drivers side and get new clips and clean it out these trucks are notroius for fuse link issues replace them with a decent gauge fuse holder there is a certian way the wires go to make it work the fuel filter should be replaced regardless if you havent because they get CLOGGED like bad man so

The main thing I can say is vacuum is extremely important on efis so tear the plenom out because most of the time they are already rotted out and are not doing anything.

Oh and the timing on these things are picky your rotor should be timed to the first right manifold bolt also the module on the distributor will go bad and it will cause extreme issues for basically no reason it's not a Chevy so the rotor goes counter clockwise not clockwise which makes it fun as a Chevy guy lol but main thing I would tell you check spark on all cylinders check your timing order on your plug wires it took me a bit to figure out how to do that also replace the plugs with motor craft plugs no other brand these engines HATE fancy spark plugs don't ask why idk.

@@bignatethehate6535 hey big Nate, so I’ve already diagnosed the ignition system on the vehicle and everything from the distributor to the PIP module all work now I think it’s a fuel issue due to the fact that when I crank the engine and give it gas to help start the throttle doesn’t do anythingshe only ever responds if I add in starting fluid

Try running it off the other tank. I have a 88 and the one tank will syphon and over fill the other tank.

Icm when they go bad you can get intermittent spark then none .does the pump run constantly when the key is turned with ignition on if so that is a sign of a failed ECM or failing ecm wich also controls injector pulse .spray either down the throttle body and see if it fires .

What about the high pressure pump on the frame rail? Is it also priming? Those tfi modules and pip sensors are finicky and cause all sorts of weird problems.

@Midnightkid00 so basically, until 1990, Ford used 2 pumps in the system. Low pressure pumps in the tanks feed a high pressure pump that's mounted on the inside of the drivers side frame rail (right near the radius arm mount). It should also prime when you turn the key.

@Midnightkid00 also just as a few easy tests. unplug the iac and see if anything changes. You could also try spraying starting fluid and see if it's starving for fuel.
