It runs for 5 minutes and then dies,trying again and wont star,wait 1hour and it starts for 5 minutes snd then dies.have new pump,new fuel filter,and coil replaced and still doing the same,what could
Have your exhaust system checked for restriction. That may be hard to do, unless you can get someone to come to you, get it towed, or have the wherewithall to do it yourself. Often, a clogged cat converter, will let enough exhaust through to idle when cold, but as the guts of the cat expand, the flow will be cut off. Not always the case, but I've seen it happen enough times to suggest it. Another way to check this, is to remove one or both(depending on your setup,) of the upstream(pre converter) o2 sensors. If this makes a big difference, suspect the cat.Also, when idling, does it start to run rough for a few seconds before it quits? If so, push the brake pedal when it begins to run poorly. An engine with a clogged exhaust will have very poor intake manifold vacuum, therefor, the vacuum assisted power brakes would feel much different. The brake pedal would seem very hard to push, as though the engine were not running. No guarantee,but that gives you some things to check. Let me know if you have any more questions. When I can't lay hands on the car, test it, hear it, or see it, this can be a bit of a process sometimes.Hang in there!
