Code 54 Help Pls

[79TransAm]

My bird is still not running... :( It's a 87 Trans Am WS6 with a 5.0L TPI engine. I actually got it to start this morning but it had a very erratic idle. and it eventually died. it acted like it isnt getting enough fuel which explains the code im getting, but when i hit the pin on the fuel rail where you can throw a gauge it shoots out real good. should i find a gauge and see what the pressure is? also the car seems to shut off when it warms up a little. any help would be great.

I'm getting a code 54:



low fuel pump voltage
OR
fuel pump relay
OR
EGR Solenoid No. 2 Failure
OR
Quad Driver Module output failure
OR
Mixture Control Solenoid - Circut voltage too high
OR

try tapping on your MAF sensor...(the black thing in between your throttle body and air cleaner) has 3 wires going to it. Also check the wires an connectors for damage. Also make sure the rubber tubes are tight and free of leaks. Those are a big source of hard starting headaches that year.
When doing fuel testing try to get a pressure and volume test.
I think the pressure should be around 45psi? and should put out at least a quart in 30sec? this is from memory and i have a bad one.

Heh... I feel like I had a similar situation. Mine turned out to be a bad coil.

True, but it did give me the bad computer code. Stupid new cars....
