Fuel Pump Electrical Circuit
OPERATION
When the key is turned ON with out the engine running, the control module turns a fuel pump relay ON for two seconds. This builds up fuel pressure quickly. If the engine is not started within two seconds, the control module shuts the fuel pump OFF and waits until the engine starts. As soon as the engine is cranked, the control module turns the relay ON and runs the fuel pump.
When the engine is cranking or running, the control module receives the Crankshaft Position (CKP) sensor reference pulses which in turn energize the fuel injectors. As a back-up system to the fuel pump relay, the fuel pump can also be turned ON by a fuel pump oil pressure switch. When the
engine reaches about 28 kPa (4 psi), and the fuel pump relay does not complete the circuit, the fuel pump oil pressure switch will close to complete the circuit to run the fuel pump.

An inoperative fuel pump relay can result in long cranking times, particularly if the engine is cold. The fuel pump oil pressure switch will turn ON the fuel pump as soon as oil pressure reaches about 28 kPa (4 psi).



You can test to see if the relay it's self is bad by swapping it temporarily with another relay. If your truck has AC then that one should be compatible. Just compare the two to see if they're the same and if so, try using the AC's relay.

!988 Jeep Cherokee MPI fuel pressure problem. New everything on/in the fuel system. Can only make it run with a jumper wire from the fuel pump to the battery. Any ideas?


Have you checked the fuel pump relay. If you haven't locate the relay and jump out pins 30 and 87 (there should be a diagram on the relay or if you look at the bottom of it, the pins should be numbered, jump out the corresponding sockets in the relay housing). If the fuel pump turns on when you do that you've verified the power feed is good and the wires to the fuel pump are good. Now with a digital multimeter check that there is battery + on pin 85 or 86. If that checks out, when cranking make sure there is a good ground on the opposite pin (if pin 85 had + on it, pin 86 should have a ground). If all that checks out you can suspect the relay is faulty.

FUEL PUMP REPLACED TWICE..NEW CAP, ROTOR,WIRES,PLUGS AND FILTER. INITINAL START UP REQUIRES EXCESSIVE SPIN OVER. WHAT CAN CAUSE THIS CONDITION ON A 98 4.0 FUEL INJECTED JEEP?


could be the fuel pump relay, do you hear the pump prime when you turn on the key? if not then replace the fuel pump relay.

2000 Jeep Grand cherokee Laredo wont start. Engine turn over . No noise from fuel pump with ignition on. Replaced fuel pump and filter.Turn ignition on- pump did not run.Jumped the fuel pump at the pump...


sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered

98 cherokee will not start but will turn over. It was running fine the day before. No pressure on fuel rail. No gauges work except oil pressure, all lights on dash work. I know it has fuel just filled up....


could be the fuel pump, fuel pump fuse, relay or wiring. Also check the crank sensor on this vehicle. They are known to go bad or come loose causing the vehicle not to start.

Changing from 98 2.5 man.tranny,to 01 3.9


WOW. You want to put a 3.9 ltr V6 from a 2001 Dakota into a 1998 Dakota with a 2.5 ltr 4 cylinder? And you want to keep the manual trans? Have you considered what you will be using for a fuel and engine managment system? If you have a wrecked truck as a host vehicle then the changover may work. But it will take patience and a lot of work. I don't think the 4 cylinder trans will bolt up but I am not sure - never tried that. However that light duty trans will probably not handle the torque for very long even if it did bolt up. Your local Auto Salvage Yard will have a changeover guide and be able to tell you if that trans will fit either engine. My recommendation is to swap everthing and change that 98 to a 01, auto trans and everything.
Good Luck
Let me know how it goes?
