I have a 88 Stang with a 5.0L the car ran fine till one day it just cut off i was told it was the fuel pump so i had it replaced with a brand new pump which i bought at autozone. After i had my buddy install the pump the car gave a hard time to start up we sprayed starting fuild in the intake and finaly the car started up ran for about 2 hours then shut off and wont start up anymore. I changed all the spark plugs and wires new cap & rotor New Battery. The engine just cracks but wont fire up if you spray starting fuild in the intake it wants to kick over but wont start can someone please give me any ideals on what it can be?

 

Well obviously it's fuel related. When you turn the key on, not to cranks, just to the run position, do you hear the pump energise for 2 seconds? If not, you could have a bad relay, inertia switch or a wiring problem.

 

Yeah when you place the key on half way with out cranking the engine you hear the pump runing for a few seconds then cuts off

 

I just re read your first post. Have you checked for spark? I thought you said it would start w/ starting fluid but you said it wants to start but doesn't.

 

Yes i checked the coil and there is plenty of spark

 

too bad u dont have a noid lite set to check for the injector pulse while cranking.......................... you might also wanna check computer for diagnostic codes. my old lx hatch ran fine one day, i shut it off and went inside to get something came back out and it wouldnt start. turned out it was the tps sensor

 

where is the tps sensor located on these stangs

 

its right on top of the throttle body. has orange green and black wires running to it. cant miss it

 

Okay thats the little round black senor with 2 screws holding it in place i found this on autozone.com
