Hey
88 XJ 4.0 auto
So my XJ left me stranded this morning, but it's not too bad jsut across campus and it's pretty cold like 20 degrees out.
I was wondering if I may have a bad fuel pump.
Here are the symptoms
The pump takes a long time to prime - followed by whining noise in rear
Will crank over and start up to like 1500 2000 rpms, but dies the second you touch the gas or shortly after it spikes up to that rpm range. (This only starts like this intermitenly)
I checked all the plugs and they are firing.
When turning off my truck it follows with the whining noise
I am gonna go buy a feul pressure gauge and test it out cuz that's cheapest way to start. Lemme know what you think, as far as I know it's the original pump. I'll prob hop right on it and change the fuel filter as well
