Customer Question

91 Jeep W YJ keeps acting like it running out of gas..sputterting. Replaced the fuel filter, brain, fuel pump...
JA: So many things can cause fuel pump issues. Some simple, some complicated. Fortunately, the mechanics we work with have tons of experience dealing with them. Tell me a bit more about what's going on so he can help you best.
Customer: Not sure what more to say! Unable to drive my Jeep. It may run fine for 10 min, or 2 min, then boggles down & act like I just ran out of gas. Sometimes it dies in the middle of the road, sometimes & can restart it. Don't matter if she's cold or hot.
JA: Are you hoping to fix this yourself?
Customer: We tried; however, many of other we know with same issue had mechanic's assisted & it just cost the more money to no avil...your thoughts
JA: Is there anything else the Jeep Mechanic should be aware of about your Jeep?
Customer: Not that I know could use a new fuel wiring harness. During some intake manifold issues, it
burnt some wires years ago.

Expert:  Amedee replied 1 year ago.

Thank you for that information. Were the tune up parts replaced? Plugs, wires cap and rotor? What about the ignition coil? How about the camshaft position sensor? What about the crankshaft position sensor?

Customer: replied 1 year ago.
we are awear of what may need replaced; however, before we replace that and every sensor....WHAT to tell which one...How to tell if a part is no longer at working capacity. What do you recommend & in what order, before we spend another 200.00 + on wrong need to narrow it DOWN plz
Expert:  Amedee replied 1 year ago.

YES, I can. You will need to check for spark and fuel pressure WHEN this problem occurs. We need to figure out of the problem is fuel or ignition related
