I've got 04 2.7 diesel grand Cherokee low fuel light keeps coming on when tank is full and on broad computer tells me 800 plus kilometres can anyone tell me why

Check the float in the fuel tank (sender). If you can remove clean the contacts, these are 2 slide tracks. You can test before placing back into tank.

All the electrical turns off for a few seconds and comes back on. The engine keeps running, no problem. But the dash lights, clock and everything resets?

loose fuse. or defective fuse for dash.
some fuses have hair line cracks in side, replace it.
some keyswitches have 2 ignition outputs.
one for EFI (runs engine)
and one more for all else.
that too can fail, we use a thing called a VOLTMETER
to find which wire is dropping out (0v) and move upstream until it dont. the bad part is between the good side 12v and the 0v side.
if no tools, all you can do is gue$$

I have a 2001 Buick Century Custom. ABS, Trac and service engine light come on after 45 minutes and stay on. I have replaced left rear main bearing/speed sensor twice and wiring harness with same result....

have they checked the PCM/ECM fuses? some might be bad or the computer itself. does the car run poorly, bad fuel economy? you could go the the emission check place to have it checked. for alot less money it will tell you if it is computer related before spending more for a mechanic to analyse it .$15 in WA State.

I have a 2006 corola. It sometimes just quits while driving it. I pull over and shut the key off for a couple of minutes then restart and is ok for awile. The check engine light also comes on when this...

Let's try the simple first and replace the fuel filter soon as we can, The fuel filter may be at the end of it's life and is causing the engine to quit working when the flow of fuel is restricted. Note the fuel pump is working harder trying to keep the fuel pressure up and may over heat causing it to fail also which mean a costly replacement of the fuel pump in the gas tank. Good luck and keep me posted, be glad to help.

Throttle/Idle/running problem - wants to run too fast, or stall out

RPM's up and down check EGR valve and sensor. EGR valve and sensor control idle. That's why your getting the surging on rpm's and this could be giving out the other codes. If mass flow was bad car will not start and the same for the map sensor. O2 sensor measures gas and air for right mixer. TPS controls 0-60 speed as in throttle respons.
