Is there a reset button on a 1999 isuzu trooper 4x4 it won't start acting as if it's out of gas but isn't already replaced fuel pump 2 mths ago


which engine? i cant guess engines, not today, too early.
what will be, will be..... fate always wins... and entropy.
so that is just 2 simple tests.
12vdc (11v cranking) to the pump , across both its 2 pins?
yes, /no of no work to ECU relay (fuel pump relay)
if the relay shows 12vdc cranking and pump
then we check fuel pressure, next.
but that is all wrong..... what do we really do, as all EFI systems can cut fuel for many reasons, besides that pump.
ill guess its a gasoline engine, and still stock end to end. (blind too)
1: head lights glow bright , key off. and cranks fast on demand.
2: key on, the CEL glows, in cluster, it must or ECU lost power.
3: fuses to ECU and pump good...???? all fuses good.
4: i connect scan tool (any tool works in usa, here) at the 16pin DLC port seen near knees of driver. i get comms now. if not say so.... if no comms now, the ecu is dead.
5: I crank for 5seconds release key and if scans show DTC errors of
P03xx codes, now you know why injection is halted, by design.
all cars do that, if up to 3 things spark wise are bad, the ECU cuts all injectors dead. (prevents crash and burn, as seen on TV by law)
so if all that is OK,?
6:then i look and see if injector 1 passes my NOID light test.
yes, then it is injecting. ECU is....injecting. ok. (did its job)
7: i then check for 12vdc (11v cranking) to the pump, if not?, I trace that wire for its obvious failure or the relay bad.
if you have 12vdc to pump cranking (good)
i check fuel pressure next. using a tool called a fuel pressure gauge that costs $20 (ask)

one could skip to test 6 first. (6 bad, start back at #1)


next time post engine in car.
cylinder count at least and displacement.
the line up, last 2 are diesel...
3.2 L 6VD1 SOHC V6
3.2 L 6VD1 DOHC V6 twin cam.
3.5 L 6VE1 DOHC V6
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4

i answered for USA car, and gasoline engine..

Chevy diesal wont start fuel pressure is good


Make sure no check engine light. If light on run diagnostic prior to testing. If no check eng. light and no start when cold, could be bad glow plugs, Take test light from positive side of battery to each glow plug post (unplug from harness before testing) if test light lights plug good . if plugs good check pump mounted driver (scan tool required) if P.M.D. good run test for optical sensor in injector pump (scan tool required). Known failure points. I am working on assumption fuel pressure tested between lift pump and injector pump. Look for white smoke when cranking, if present fuel entering cylinders. I can't offer anymore help without further info. Hope this helps.

2002 Chevy Silverado 2500 diesel (turns over but won't start)


Check and make sure your glow plug controller is putting out voltage to your glow plugs, make sure voltage to your glow plugs is cycling. if it is not, at the front of the engine there is a temperature switch, if this switch is not working your glow plug controller will not work. also make sure you are getting diesel to your injector pump, if you are not, there is a high pressure switch at the back of the engine right behind the glow plug controller, if this switch is not working, your injector pump will not get fuel. also make sure both batteries are fulley charged, if one is low, your diesel will never start. you can jump out these switches, if your truck starts after bypassing, just make sure to replace them. i have a 1993 silverado C3500HD 2WD. good luck!

I have a 95 Chevy silverado 2500 6.5 diesel auto it will shut of or not excellerate smothley from idle to 35 mph it only happens every other day I have a new pmd that I bought new and installed new...


They all have to sit for a minute because of the glow plugs. Some diesel don't send power to the starter until the glow plugs run for the pre-determined amount of time. There are many things that could be causing this. Fuel filter, clogged injectors, fuel pump going bad or bad connection to fuel pump.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

1996 silverado 5.7 vortec cranks but wont start. fuel pump, gauges, "idiot" lights, blinkers do not work. flashers and all the rest of lights operate. Just replaced coil and this happens


Had the same problem with my '96 Silverado with 350 Vortec. The truck would only crank. It would start if fuel was poured down the throttle body. Could not hear the fuel pump hum. Fuse was good, but could not hear relay click. Relay was good, Did some electrical wiring trouble shooting. Turned out that one of the connectors that clasp onto one of the pins of the fuel pump relay wasn't making a good connection, too loose. I just stuck a peice of wire into the connector and pushed the relay back in. Relay clicked, Truck Started. It's been more than 4 yrs. since I made that McGuyver fix. Still firing.
