Having problems with your 1994 GMC Sierra ?

1994 GMC Sierra 2500 won't start

\015 Everything in truck seems to be working fine except when I turn the key, it turns over, has spark but will not fire. Is this a fuel pump issue to where I would need to replace it or could it be as small an issue as the relay?\015 Posted / edited by AnonymousUser on : 10-12-2018

Answers :

Definitely could be something smaller. Like a relay....even a filter.
\015\012Few things to try:
\015\012Just turn the key to on, not start and see if you listening to the fuel tank if you can hear the pump going. If not, its either the pump or the relay.
\015\012Most of these trucks have another switch that kicks in after the enigine is started and runs the pump so you may be able to spray starting fluid in it while cranking it and get it to start. Then the other switch may kick in and run it. that will let you know if its the relay or what. Let me know what you find. I just replaced a relay on a 93 and it was only $8.....worth a try. Also, there will be a fuel pump fuse, probably close to the relay, could be that!
Have a 94 gmc serria 2500 it cut out and wont do nothing i brought a new battery and still nothing no fire. do anybody know how many computers does this truck have?
