Car starts but cuts off quickly..plz help Options

[diZzyGOomba]

I need help..lol. I have a 94 Gt and its been having issues lately. I can start my car and drive perfectly fine until i get some place and try to restart it. when i try to restart it....the engine will crank and start for a split second and then shut off (also makes a weird grinding noise when it shuts off)...or sometimes it wont even start at all. But when this happens...if i try and start the car and step on the gas at the same time..sometimes it'll start and drive somewhat okay.

I assumed it was a fuel issue so i changed the Fuel pump and fuel filter hoping it would fix the problem but it seems to have popped up again...any suggestions or ideas that can lead me in the right direction? Any advice will be greatly appreciated cuz i need my baby on the road again!

Make sure your getting fuel to the motor when its not wanting to start. I had a relay go bad and it only worked when it wanted to. Replaced filter and pump before I figured it out. There should be another relay in the ac slot or something aux you can use to try it. If that doesn't help I believe the coolant temperature sensor can cause this issue.

thanks for the info! ill check the relays out this weekend between nfl playoff games of course! lol

Go Broncos! let me know what happens with your car

[diZzyGOomba]

is there a specific relay i should be checking for? like Main relay or injection relay? sorry if its a stupid question..just trying to narrow it down.

efi relay in the fuse block under the hood. try that one out first. Also coolant temp sensor is like $20ish. So not to0 spendy to try out and see if it resolves the issue. Also when you bought your new fuel pump was it oem or aftermarket? and if aftermarket did it come with an adapter wire? one that goes from the new fuel pump to the harness that the old pump used to be connected directly to?

Sounds like the efi relay. When you drive for awhile... It will warm up and when its warm... It doesnt like to give a good connection.

It was an Oem one, so no adapter wires or anything was included..just new clamps and a short hose to replace the old ones. I also replaced my coolant Temp sensor before thinking that could be the issue as well..but not luck lol..ive been busy all weekend so hopefully i can get to checking the EFI relay and others out tomorrow before work! thanks again guys..i really appreciate it

and u posted before that i can use a relay from the AC or another Aux one to replace it..Can this be done for any relay that goes bad or just the EFI? just in case it isnt the EFI...sorry again if its a dumb question..im not the most mechanically inclined person in the world

[Roadrash]

just match up the numbers on the top of the relay. i believe there are 3 relays that are the same as the efi relay. pretty sure the AC is one of them. its located in the smaller fuse block under the hood to the left of the radiator if your looking into the engine bay standing in front of the car.

Okay thanks alot ill def check it out! crazy thing is though ..is that my car hasnt been acting up ever since! smh gotta love it!! but ill probably just end up replacing the relay anyway just in case

[Roadrash]

Yeah it would be a good idea to put a new one in the car and a spare in the glove box. I'm fairly certain thats your problem. Rockauto.com has the relays for 15 bucks a pop.
