1990 jeep cherokee keeps burning out the fuel pump, replaced 1st fuel pump due to no fuel pressure, replaced 2nd fuel pump due to wires on the pump blistered and not working after 4 days of use.

I had a problem with a 1990 once that was strange like that. Went through 4 pumps before finally figuring out that the baffle inside the tank had come free and was knocking the pump around causing it to short. Inside that metal tank isa baffle set up to reduce the splashing around and movement of the gas at teh pump. If it comes free it will knock up against the pump and short it out. When you pull the pump out use a wire to reach around inside the tank and see if you can find a part moving around freely, if you do the only choice if to replace the tank. There is no way to weld that back or reattach it safely, J-B weld won't work and obviously welding is not an option.

We replaced the engine on my 1990 Canmaro but now the fuel pump won't work. We connected a wire directly to the fuel pum and it works and I also checked the relay and there is no current going to it....

the pressure regulator is not reporting to the ECM to energize the relay for the fuel pump
by having a direct power to the pump , eventually the fuel pressure will overcome the injectors and they will put out more fuel

I have a 1990 Chevy Astro van that stopped running on me while I was driving it. I towed it home. I replaced the fuel pump and it ran for a little while and started running very rough. So I bought another...

You say you replaced the fuel pump, what about the filter? If the filter is clogged it can cause this as can ignition. Since the car started for you after the fuel pump was changed the original problem was the fuel pump. But you should never change the pump without installing a new filter.

Acura integra 1990 turns over fine but doesnt start

for you to check if it is the fuel pump, see if there is fuel running out of the hose if you remove the fuel filter. Another is to directly connect the pump to the battery. If the pump works that way, then it could be a efi relay issue which is found underneath the dash or a wiring issue.

Replaced in/tank fuel pump.

I have had problems with my 89 prelude. I found that the problem wasn't with the fuel pump, rather the master relay. You will have voltage at the fuel pump with the fuel pump dicconnected, but when you connect the pump and put a electrical load on the circuit, the voltage drops. check current with the pump running and see if this is the case.
