This is a post that I put up on FEOA & I have not recieved any responses that help. I know that CEG has some of the most knowledgeble people on the net so I'll give you guys a shot. Any help would be appreciated. I've been struggling w/ this too long & i have other projects that I want to start on. here is the post. Originally posted by "OB1":
Alright first off its an 89 LX, ATX, CFI. I started by checking for fuel & spark. Its firing just fine, So I started checking the fuel system b/c I'm getting no fuel. Alright I've replaced the fuel pump( yes I got the right one for CFI), the inertia switch, the ECU, The entire throttle body assembly w/ TPS and everything, various relays under the hood, & checked fuse panels. I can remove the fuel line from the side of the throttle body & i'm getting fuel there, its just not coming through the fuel injector, I'm pretty sure that its electrical. I've replaced everything that I can think of but I'm hearing that there is a relay under the dash that controls the fuel pump. I've racked my brain on this car & its kicking my but! I can spray fuel in the TB & it will crank & idle just fine. If anyone has any wiring schematics or any Ideas for me I'm all ears.
Thanks in advance

Step 1. Measure the fuel pressure with a guage. You should have at least 35-40 psi after pump prime.
Step 2. Verify supply power to the injector(s).
Step 3. Use a "noid" (injector test lamp) to see if the injectors are firing.
Verify the TPS and its wiring are not defective such that the PCM thinks the throttle is fully depressed since that would cause to PCM to disable the injectors.
