'89 cherokee wont stay running, its starts rough and runs for a few seconds and point blank shuts off, what are some things I should look at?

 

i'd start with fuel pressure

 

Yeah that is what I have heard, i was just wondering if there was anything else.

 

The "ballast resistor", the cream colored resistor located on the fenderwell I believe.

If it is bad, it will shut off fuel. You can bypass it temporarily (jumper wire) to see if that resolves the issues; bypassing is safe, the resistor was eliminated in later models. It is there only to reduce noise on the fuel pump circuit.

 

Check your 02 censors. Had this same problem in my vehicle and it was the 02s...

 

how do i check em?

 

Go to any auto store around you and get them to run a code.. If it's a 'lean' code it's probably 02

 

This is what it was on my '89, but the ballast was fine, just the connections to it..

 

If it was mine, I'd start it,let it die, not turn the key off or try to start again, go around front and check for fuel presure before I did anything else.

 

Not the O2 sensors. They're not even in play upon start-up. Ballast resistor and fuel pressure is where you start.

 

Renix does not store codes, and it absolutely is NOT the O2 sensor that's the problem. You're talking 2 very different fuel injection systems here..

 

I would check the resistor connector... and I would also change your fuel filter... When was the last time you did a tune up? Does your xj have good spark?

 

It was a pretty week spark last time it was checked but thats because the distributer was all messed up or so I thought

 

I have concluded it is the fuel pump!!! Not to excited to work on it or pay for it but, bring it on!

 

fuel pumps a pc of cake on a 89
