1996 pontiac grand prix crank no start. fuel pump was not making noise. so I pulled the the tank and found the pump at the wire connector was black from heat and melted. i replaced the fuel pump. i can hear the pump running when the key is on. but i have no fuel pressure. i've checked at the pressure releaf valve nothing there i checked the fuel line at the fuel pump (on top of the fuel tank) turned the key on and no fuel comming out/ pumping. if i could get an answer that would be great. thanks....

Wires on the pump backwards.
Testimonial: "Thank you so much the pig tail that I received from the parts store had the wires crossed. i was able to switch them and got the car running.
Thanks,"

What engine ? could have 3.1 or 3.8 L No resistor ? for what ?
Noticed no Speed Cont. fuel pump relay. What are you talking about . Are you talking about no control for the fuel pump relay from the PCM/ECM engine computer ? The PCM Energizes the fuel pump relay for two seconds when key is first turned on . Two second prime of fuel system . When cranking the engine the PCM/ECM will only energize the fuel pump relay if it see's an input from the crank sensor .

Open the trunk, pull the carpet back to reveal the access to the fuel pump. The gas tank pressure sensor is located on top or the fuel pump. The connector has 3 wires, 1 black and 2 colored. Pull the plug off the sensor, put jumper across the 2 colored wires, tape it up with electrical tape. Replace the access cover, the carpet, close the trunk and never see that "CHECK GAS CAP" message again.
odds are the pump is bad, but it could be the relay or wiring. Try pulling the relay out and using a different one. You could use the horn relay, for example. If the fuse blows again, take the connector off the pump and interrogate both sides with an ohmmeter. The grey and black wires go to the pump. The resistance between these should be really high on the connector and should be at least a few ohms on the tank side. Whichever side has no resistance is shorted. Am I making sense?
replace your fuel filter and buy Z MAX (only thing i trust) fuel and engine system restore ( about 35 bucks at any auto store but so worth it). what has happend is the fuel in the tank is dirty or carmalized, basically the car had been sitting for a while and the fuel seperated in your tank. normal conventional gas is not strong enough to break down deposits. and when you replace your fuel pump, make sure the whole wiring harness or the actuall fuel pump harness is replace. other wise you keep blowing your fuel pump and/ or keep backfiring
May have to get a code reader for this one..... Bad coil, open wire on crank shaft sensor, fuel pump, are among possible problems..... Try a bit of starting fluid, not much of too often mind you!
