Please help me!! I have an 87 t-bird 3.8 that wont start, the alt. is bad so it wont charge the bat. one day I shut it off came out later and it wouldent start so I got a new bat. and it still wouldent start. It turns over but wont fire, I noticed no fuel pump sound when I turned the key on so I jumped the pump relay in the trunk and it works, if I let the pump run for a few seconds then try it, it would run for about 4-5 seconds then die. I opend the fuel bleeder and turned on the pump and it pumps plenty of fuel. The injectors are rather new along with whole top end of the motor(head gasket went). Is there a relay somewhere else im missing or injector fuse, bad computer. Should I take it to the junk yard or what?? Thanks for any help!!

I'm not 100% sure of an answer so your problem, but you said the alternator was bad? Did you replace it? I read that you replaced the battery since it was dead, but no word about the alternator.

Check for loose electrical connections somewhere - if you just rebuilt the top of the engine, may have missed hooking something back in. And do you have spark?

Just a few things to think about/check on. Hopefully others will have more ideas or things to check out and try.

You said you jumped the pump relay, doing that for a few seconds, is NOT going to fix your problem, you need to replace the relay, and check your wiring, and fuses. I would say that's your problem, you have a messed up fuse or relay, and the pump doesn't run, so you jump it for a few seconds, which pushes fuel through the lines, and so you have enough gas to run for a few seconds, but not enough to keep it running.
