jack Robinson Posted April 18 Share Posted April 18 Hey so I got a 92 comanche eliminator and I've been having starting issues lately. So off a cold start it seem like its not getting enough fuel and struggles to iddle but after a minute or so smooths out and runs fine. Has good oil pressure the only thing I can think of is I have a bad battery that's in it now. Any help/suggestions would be much appreciated thanks Link to comment Share on other sites More sharing options...
89 MJ Posted April 18 Share Posted April 18 What happens if you cycle the key a couple of times before trying to start it? Have you verified fuel pressure? Link to comment Share on other sites More sharing options...

No code and where would I check fuel pressure? but I think it was the throttle sensor, my case broke and it still works but just checked and it was loose again so I'll see if that fixed it tomorrow.

Cycling the key a few times would have the pump run a couple of times to make sure the system would prime. There should be a schrader valve along the fuel rail where you could hook up a gauge to check the pressure. Link to comment Share on other sites More sharing options...
ghetdjc320 Posted April 19 Share Posted April 19 Iacv could also be an issue. A good TB cleanup may help. Link to comment Share on other sites More sharing options...

Good place to start. Pun intended. Link to comment Share on other sites More sharing options...
jack Robinson Posted April 20 Author Share Posted April 20 That wasn't the problem it now does it when warm. So I start it and I have to give it gas to start then stumbles for a bit but then smoothes out and acts normal. So still at a loss Link to comment Share on other sites More sharing options...
jack Robinson Posted April 20 Author Share Posted April 20 My fuel rail does not have a Schrader valve on it. And I can prime with a couple of key turns but doesn't change anything Link to comment Share on other sites More sharing options...
