Seems like you got all you need , check the sparkplugs the engine may be flooding itself, (one guess),

97 Oldsmobile 88 after driving once motor is shut off will not crank until cool, had the control module tested it came back good, replace fuel pressure switch and still will not crank until cool?


You will need to replace the crank angle/position sensor near the crank pulley. A photo of the sensor is attached. The sensors wear out due to heat and cold cycles and internal corrosion.

2001Toyota Rav4L 1AZ FSE won't start test crank and cam sensor good high pressure pump good no pulse from the injecter wire using pulse light could you tell what's wrong.


No pulse means computer is not getting something it wants. Do you have spark at plugs? Correct fuel pressure? Security system needs reset?

Have gas ,spark and compression no run


FUEL INJECTED CARS REQUIRE LOTS OF FUEL PRESSURE. THE ELEMENTS NECESSARY FOR STARTING ARE: SPARK ,COMPRESSION, FUEL, FUEL PRESSURE, TIMING AND CRANK AND CAM SENSOR SIGNALS AT THE PROPER MOMENT AND STARTER MOTOR ENGAGEMENT. FUEL PRESSURE REQUIRED IS USUALLY 30-50 LBS DEPENDING ON THE TYPE OF CAR. THE COMPUTER MUST PULSE THE INJECTORS.

What generates fuel injection pulse on a 1994 geo metro base model? I have replaced alternator, TBI injector, and ECU. Checked relays, fuel pump and filter. Feed and return line are clear. On startup I get...


The PCM (ECU does that) its part of what is called EFI, electronic fuel injection, it's a computer, that gets inputs, and uses those inputs to injector perfectly at ALL times.
what engine? 3cy. or 4? is it TBI injected or MPI injected
1 injector or 4? we need to know that first.
does it run on test fuel for 3 seconds.
when was last time it run perfect, last week last year. what?
first off stop guessing, you can go broke that way.
want to diagnosis it? the steps are easy. if fuel is good..
  1. fuses good.?
  2. CEL lamp glow keyon, if not ECU is bad. or bulb , it must glow.
  3. compression over 150PSI on all cyl. (w.o.t = wide open throttle)
  4. do a 60k, mile tune up yet, filters, spark,. and cam timing belt.?
  5. if not, why wait?
  6. 6: is spark good tall cylinders not just 1? is the timing way off if yes, the cam belt did slip, do not fiddle tiiming, fix the belt. first.
  7. ok it now magically runs on test fuel for 3 seconds and sounds great. so we do fueling last.
  8. fuel pressure tests are next. takes $20 gauge got one?
  9. ill stop here, as fueling tests are long play.l..... ask. if you can get to step 9,

I think all 94 metors are TBI engines, one injector
up to 1997 inclusive.
then the 1998 offered 4cyl, MPI injected engine.


have you learned how to use flash codes (DTC) yet?
insert jumper , key on, see CEL lamp glow and flash 12s'
the crank for 5seconds, see if the flashes go to 41 or 42?
bingo if yes.
the TBI allows the mech to watch injection, at the TB.
with top hose off. you can watch it inject as person 2 cranks.
does it?
the ECU brain cuts fuel at the first sign of:
  1. lost spark (to stop fires)
  2. lost Cmp sensor, same .
  3. TPS ground wire busted and ecu things foot is W.O.T (super secret unflood mode) (or TPS cracked in half inside)
or total loss of fuel pressure.

No Injector Pulse


run fault codes as there is a problem sensor in the system. volts at the injector is suspect as the voltage will vary with the fuel requirement.

Fuel pump went bad fixed that now my car wont start


Now you check fuel pressure at motor with a gauge

Also check for spark & injector pulse while cranking

No spark nostart on 1997 maxima with 1998 tranny


did you replace the knock sensor from the old one to the replacement one. ? double check the sensors are the correct ones fitted to your original engine are on the new replacement, also check the connection plugs, sometimes these cannot connect fully if have become weak.
