Ok I changed fuel pump. When I disconnect fuel line at rail gas shoots out so I guess it is working. It cranks but won't fire Iprimeda bunch of times When I pour gas in the throttle it starts then dies. I have spark. What next?? I switched relays but nothing please help. Thanks

Can you hear the pump running when you turn the key? It should "buzz" for about 2 sec then shut off.

trying to diagnose a problem without the proper tools is hard. If you had a fuel pressure guage it would tell you right away wether or not you had fuel to the fuel rail. then you can go from there,
Now its a guessing game. shot in the dark make sure the fuel connections are tight. make sure the electrical connections are tight.

Definately need a fuel pressure guage. It takes a considerable amount of pressure to feed the injectors. It may initially pressure up but the volume might not be there.

Ok ordered gauge will check pressure if pressure not enough what does that mean being that I just installed a new fuel pump thanks

OK got the fuel pressure guage and she is reading around 48!! which seems to be OK- qucik question since she sat thru the summer fall- is it possible that it is old/bad gas??- although she was at 1/8th of a tank whens he died - i put 4 gallons fresh gas in and still nothing??- what do I look for next??

- I rechecked spark and have plenty- I put a 12v test light into the injector wires and get power when cranking- SO if I have spark and plenty of fuel pressure why wont she start???- Please help--thanks

update- pulled fuel rail- Injectors are firing and squirting gas-BUT when I crank her over a few times the spark plugs remain dry???_ I would think they should be wet????- what would cause this problem??- thanks guys I am at my wits end with this!!!!

Guys any idea why the plugs remain dry even though injectors fire fuel. This must be my problem. Thanks

It sounds to me like everything is working except you are not getting gas. I would take the pump back and try annother one. What brand pump did you get? If it was an Airtex try a better brand.
