I hive a 1990 1500 Silverado z71 off road ran good for about 3 minuets then would start to die out then die after cooled off would do same thing so I changed full pump and filter then realized there was no...


Cannot determine from the description of the problem if rewiring power to pump resolved the loss of the electrical power or not. Now when it dies, is there still a loss of electrical power? If there is still a loss of electrical power, ensure that the new wiring is connected to the 'Engine Switched' side of the power system. In other words, only when the engine is turned on, power is applied to the fuel pump. If power is good, mostly likely there is a clog in the fuel system (lines) between the pump and the fuel injectors. It doesn't necessarily mean trash was sucked out of tank, today's ethanol gas can trash a fuel system from the inside out. Being a 1990...vehicles back then were less compatible with ethanol. If pump has power and running, fuel lines may need a good flush (multiple flushes maybe to get it all). When it quits, a simple pressure test at the injectors may help determine if fuel is getting to engine. Keep it simple...walk the dog. Make sure you've got good pressure at pump, follow fuel line hand over hand to the next connection, test pressure again, keep going until you find loss of pressure. Good luck...these type of problems are not fun to troubleshoot, not difficult either, just time consuming.

1989 lesabre stumbles and dies


I agree it sounds like the magnet for the cam sensor, or a problem in the wiring harness.
I don't think the engine will run with the cam sensor disconnected since it needs that signal to set base timing. It can run without the crank sensor once the engine starts.
There is a slight chance the timing chain is getting loose and affecting cam timing too. You may be loosing plastic teeth on the cam gear.

1989 ford f150 loss of power


1989 is fuel injected, on the intake there is idle air control valve, make sure this is not dirty, also you may want to check the coolant temperature sensor, if the engine thinks it is warmer then waht it is the fuel air ratio will be off and your truck will run bad.

My 206 1.9 diesel wont start


a diesel engine can only cutout when overheating, loss of diesel fuel and air leak in the fuel system. if you know how to bleed or ask somebody to bleed right after it stall, then start the car, if it starts immediately then it is sucking air.

No power


your catalytic converter could be plugged up. try reving engine in neutral and if it sounds labored or slow then this could be your problem and have the exhaust checked. If exhaust cant escape out of your tail pipe then you cant accelerate quickly or at all.
