[BigBumperNick]

Try an engine swap...mine works perfect now rofl.

I am an idiot. I totally forgot about it's location!

Sorry Nick.

I stole this picture from MR 325's for sale post because it is the same car, hope he doesn't mind. The relays are next to the afm/intake under a black plastic cover.

I'm refering to the suggestions that have been made in this thread...so we continue to provide feedback.

Where does he live? Micah and I may be able to come out and join in the fun.

Car is stuck in Grayson atm...

It's at the climax where its about to start and it will not. It cranks fine, like it should fire immediately. Just doesn't get the that top point

We bought new rotor, distributor, spark plugs and changed out:
-coil with a known working one (it does fire)
-spark plugs (do not fire)
-rotor
-distributor cap
-ecu
-crank reference sensor

Now I may not be the best when it comes to car mechanics, but I read the main relay, fuel relay, etc were either white or orange. These definitely don't look like they are near fuse box. Could it be possible they were shoved under dash? I feel retarded, I just need some guidance lol.

Well what has been checked/not checked?

[dinanm3atl]

I will tell Nick to check that. The issue is the car drove back from Alabama, drove all over for thousands of miles, drove to Tenn, tail of the dragon, drove home.

Bam. Won't start.

Forget about what Bentley or any other source says. The correct FPR has its rating printed right on the housing. It says 3 bar. 3 bar is 44 psi. So if your FPR is allowing 50 psi (and you trust the gauge) the fpr is faulty. And the car is getting too much fuel.

Another thing. If you have fuel pressure at the rail, you can rule out the fuel relay. The fuel pump is running, otherwise you wouldn't have pressure.

Dude, i run 50 psi with my m30 and 19lb injectors, why does my car start right up?
Halston, where did you get the injector harness? Mark put in an early model harness in his 91 when he replaced his motor and it wouldn't start. He had to switch back to the original harness. Also, make sure you have the right connections at the diagnostic port. micah swithced the two that are held in the bracket by mistake, and his car was "dead in the water" until he realized they were switched.

Known good one from a running car was swapped.

Swap the plugs from the crank sensor and the spark pulse generator. The plugs are the same and if they were off at the same time they could have been reversed. The car will not start if they are reversed. They are both inductance inputs so it will not burn anything up.

I had the same issue with my fuel pressure and had to change the FPR but mine still won't start.

Check the crank reference sensor, the wiring, and the connector under the diagnostic plug. Be sure the wire has not been cut by the fan pulley.
