Question about Cars & Trucks
Posted by Anonymous on
Sounds like you have a bad or lose ground , lose connection . Did you check the connections at the alternator ?
Two minute Voltage drop test everybody should learn> and use on every car> they work> on..
1. measure from the positive battery POST to the negative battery post.. 14.1 to 14.8 volts is expected. engine running !
2. measure from the Negative battery post to the engine block... 0.04 volts is expected..
3. measure from the negative battery post to the body........................ 0.02 volts is expected.
4. measure from the ENGINE BLOCK to the BODY ............................... 0.02 volts is expected..
If you get more than the 0.04 or 0.02 volts... you have a bad ground between those parts.. a little over can be do to an undersized ground wire.. this test takes about 2 minutes to do.. including the time it takes to get the volt meter out. It will find all the gremlins... save> your hours of work chasing ghosts. Good luck an hope this helps !

Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.

this is a common and serious problem with tracker/sidekick.
there are 3 solutions1:
ecu is bad and over loads the power feed.
fuel pump shorting and overloading feed.
one of the other solenoids , doing this same thing.
send me email link and i can send you a schematic but
its here anywhy.
and now your answer the main relay is clipped directly to the
bottom of the ECU on a bracket.
one has a green socket (fuel pump relay ) and next to that is MAIN.

check all battey connections and system grounds. Check that the battery has 12v and holds properly when load tested. To check charging system, don't disconnect any battery leads...put a volt meter across the battery. when running, you should have at least 12.9v and volts should not drop. (usual reading is generally at or near 13) at idle with all accessories on voltage should be close to that as well. voltage should not exceed 14.Also make sure that drive belt is not slipping.

You may want to try pulling connections off BCM (body control module) and cleaning them with contact spray cleaner or similar & re-installing. Sometimes you'll get lucky & this will cure it, without replacing BCM.
