Engine cranks. sparks but does not start. fuel pressure ok

Engine stalled with a full tank of fuel. No spark at all. Fitted a new distr. cap and sparkplug leads. Sparks now. Fuel pressure good. Seems not to get fuel on the plugs. Fuel filter clean. Firing order 153624. All fuses checked and okay. Check engine probe flashes as follows. 1 space 2. Thereafter 5 flashes period 5 flashes. It just just want to start. What can the problem probably be

Have you replaced the crank sensor? The crank sensor on top of the trans. bell housing does control the injector pulse through the ECM.
The sensor is a common problem with the Jeeps. Sometimes the sensor stops working when the engine is hot and will start again when it cools off and sometimes it dies from oil leaking on top of it or it just dies.

I have overhauled engine for Isuzu bighorn 1998 petrol/gasoline engine. the 6VE1.timing belt is ok. Still it has a had start.


is this the Single head cam or twin version?
no photo of engine, so answers will be weak.

double posted. is this the single cam or twin cam engine?????? per side, the twin cam has 4 cams. 2 /bank.
i can not understand your questions, at all.
ok you overhauled the engine,
nor can i understand , still hard start.
does that mean it cranks slow and turn runs and drive perfectly ?
or cranks fast, but hard to start and runs perfectly?
or does that mean it cranks fast, starts, then misfires and runs crapppy-pappy?
hark, the devil really is in the details, no?

Generic answer.
all the wires and sensors , hoses not put back correctly.
oil full, coolant full, fresh gas in tank,
then you crank engine with no spark (I pull fuses)
and the crank it until oil pressure is good. yah, do that.

if really savvy, we check for top end oiling next. cranked only.


ok looks like oil pressure is good,(I don't want to wreck a new engine) (also check compression on a new engine, to see if we messed up., if not 150psi or more, you timed it wrong)



then we crank it, ok, it cranks and don't start
I check spark and it's timing using my timing light, it's wrong, i retime it, no and its ok. as is ..
ok sparks good, on all 6 cylinders. checked carefully and for static time.

so now start engine on test fuel,
if fails, see above for why.!
ok it runs for say 2-3 seconds and stalls. good.
We yell at the gas engine gods. O'BOY my engine seems to be OK ! progress....

next is fueling , ill stop now, as typing a book on fuel injection
is not easy here.
but fuel pressure is next. on all EFI engines. as is good fuel.
when did car last drive perfectly, 1 month ago,
10 years. what?
if long ago, the gas is bad. as are related parts all gunked up, like filters, and injectors.
and even the pump, or its sock packed in GUNK.
as you can see we have no history on the car, so.
really anything is possible. even vandalism.

btw we never just throw and engine in a car.
we check.:
1: compression, gee even sitting on a pallet.!
why install (6hr labor) a dead engine,?
2: then cranked oil pressure, spark/fuel off line.
same reasons.
3: then if all that is ok, I do check top end oiling now, if not any top end, the cams will not last very long. they will smoke and seize up in a flash.

this is how its done correctly, ask how.

Replaced ignition module, spark plug wires, distributor cap, fuel filter, and thermostat. car starts then after a while you turn it off and try to restart it, but all it does is crank, will not turn over....


COULD BE FUEL PUMP.CHECK FUEL PRESSURE SHOULD BE 40 - 47 PSI. WITH NEW FUEL FILTER. IF FUEL PRESSURE OKAY.YOUR SPARK PLUGS COULD BE FOULING OUT BY LEAKING FUEL INJECTORS.CLEAN FUEL INJECTORS BY ADDING A CAN OF SEAFOAM TO 3/4 TO FULL TANK OF GAS.WHEN YOU HOOK UP FUEL PRESSURE TESTER WITH IGNITION SWITCH ON ENGINE OFF FUEL PRESSURE SHOULD READ 40 PSI. TURN OFF IGNITION SWITCH IF FUEL PRESSURE DROPS FAST YOUR FUEL PUMP CHECK VALVE BAD.IF FUEL PRESSURE DROPS SLOWLY IN TEN MINUTES TIME FUEL INJECTORS IS LEAKING A NEED CLEANING.INJECTORS SPRAYING TIP CLOGGED WITH CARBON BUILD UP CAUSING THEM TO LEAK DOWN WHEN ENGINE OFF.

Van cranks but will not start


Hi, if the engine cranks over normally when you attempt to start you car, but the engine does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION. The engine needs adequate fuel pressure, a properly timed spark and normal compression to start.

To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. IF it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.

Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.

Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine.

1997 gmc savana 4.3, wont start ,has new fuel pump, new pressure regulator, new spark plugs , i cleand up the maxi ijector, looks ok no leaks,i do have spark and fuel but still wont work any ideas


only 3 things will cause this engine not to start (crank and not start) fuel, ignition, timing.
You haven't mentioned the engine cranks over or not, so I have to assume it cranks over.
Possible timing chain or the crank sensor on the timing chain. Have you checked this? you need to remove number 1 spark plug & when the piston is in the full top position on compression, remove the dist cap & see what spark plug wire the rotor is pointing to inside the dist cap. (I'm sure if you google checking for top dead center you'll find the proper procedure)

Crank Sensor is the likely issue. It does not throw a code. Key indicator is the call stalls all the time. R&R sensor.

Check the fuel pressure. A slight dip in pressure will keep the engine from starting. When is the last time you did a tune up? Even if you are getting some spark you might not have enough. New plugs, wires, distr. cap could solve this problem. Or try a new fuel filter. When diagnosing a car problem always do simple cheap things first, as this usually ends up being the cause.
