If i'm not mistaken there might be the fuel pump relay mounted on the firewall. you might've hit the connector on the relay when doing the spider.

SOURCE: GMC JIMMY NO START BUT GOT SPARK AND FUEL

try the oil pressure switch, that was a common problem on Gm trucks when I used to work on them, the oils switch was bad and woulden't allow it to start and the ones I worked on were on the back of the distributor.

SOURCE: 1987 GMC sierra , no fuel pump power.

The inline fuel pump fuse on the passenger side firewall is good? Are you jumping it with 12 volts at the test lead or the fuse?

Will a 1995 jimmy 4.3 start if the feed fuel line and return line are switched.


The lines are different sizes and if you did... it would dead-head the pump and not start!

Will turn over but it wont start


What is the fuel pressure? these trucks need a certain amount of pressure to start, if low just 3psi it will not start, if you are sure the pump is good then you may bad spider injector. check fuel pressure first and also try spraying starting fluid into throttle body and see if truck starts. the pump needs 60 -66 psi to start the truck.

93 Jimmy with 4.3 vortec, Won't start, no spark. Changed cap, rotor, coil and ignition module. What would be the problem.


Have you checked your fuel pressure? Can you hear your fuel pump buzzing. Remove your gas cap and have a helper turn the key to the run position while you have your ear close to the open tank. If you don't hear anything you have a fuel related issue. Even if you hear the pump buzzing you need to check the fuel pressure as it may not be making enough pressure. If no buzz you may have a bad fuel pump, pump relay, or wiring problem to the pump. That is where I would start.

Car needs starting fuel to start but then runs ok.It is a 94 gmc jimmy V6


I'd try a new coolant temperature sensor. It may be telling VCM that engine is already warm, so no need for extra fuel to start cold.

I have a 1999 Gmc Jimmy and it wont start. It turns over you spray some starting fluid stuff in it and it fires up but then dies. We changed the throttle body sensor the crank sensor. Can anyone tell us...


Sounds like a bad fuel pump. If you turn the key on and don't hear it run, it is the most likely cause. You may be able to smack the tank and get it working again, but will need to be replaced. If not, look for power and ground at the pump connector when key is on.

Hard start when cold/first start in morning


The pressure relief valve is in the spider fuel injector not the fuel pump. We have had our 94 gmc jimmy for 4 years & have had to replace the fuel injector 4 times which cost right at $500 each time for the part. Yes the spider fuel injector cost averages around $500.

Could be either fuel pump or fuel injection system (spiders).. especially if neither have been replaced yet.. also, suggest you have computer checked for possible malfuction. Good luck

1994 jimmy fuel shutown @spider?


Hi

A very common failure on these is the CPFI unit , or SPIDER as people like to call it.

There is one single injector which feeds each cylinder via a pipe and poppet. The injector becomes blocked and the engine won't start or run.

Before you go condemning this though, just make sure you have good fuel pressure because the fuel pressure regulator or fuel pump could also have a hand in the problem. Make sure the pump is running, and if not then check the fuse, the relay, and the pump itself.

Very best regards
