A 1988 bmw 735 i does not start and floodes the spark plugs

I have checked the spark plugs and the gas flow everything seems fine but for whatever reason it floods the spark plug.i think the gas flow system is reversed i am not sure but it enters through the injectors and return from the top where the fuel pressure regulator is.would you please illustrate the gas flow system and could you help me find out the problem and the solution of course.thank so much.
Cheers

The fuel system is correct the problem could be a simple rubber pipe come off the inlet manifold causing the auto choke to stay on ,this is an ancient vehicle even by spanish standards and on the inlet manifold is a rubber pipe that runs to ignition module for the advance ****** and i think this may have come away from teh manifold where its perished and broke ,have a good look for it because i have had this before on these cars and the black smoke was bad and it just choked its self up

    sorry dont have access to a workshop manual for every motor ever made ,but have a look at the injector rail this is the metal pipe that delivers fuel to all the injectors ,its on the end of here that the valve is ,also check all the thin rubber vacumn air line hoses as one of these could be running to something and its perished which is causing the problem

1988 jeep Cherokee Laredo won't start turns over ,has spark, gets fuel


no engine size stated, (so i toss coin, 4.0L) 5miilion strong.
the 1988 is the gawd awful French RENIX fuel injection.
i owned 2 of these pigs. (sure it runs) but sux.
why?, no CEL lamps , no flash codes, no OBD1 , no OBD ! anything.
only the very old and rare factory and dealer tools can scan this pig.
lets do this better?
in vivid details.
NO start 101: (order matters too)
  1. compression at spec, on all 6 cylinders? (old engines do die)
  2. spark at all 6 spark plugs good,? not just 1.
  3. car is tuned up. spark plugs.cap rotor, wires, and filters?
  4. the ign timing light on #1 wire, shows spark landing near TDC 0 degrees or under hood stated spec. (open hood look up )
  5. i now check for flooding, is it? spark tips , TALK to me.?
  6. yes, then check fuel pressure. next.
  7. no, then are they dry, you said wet. ('gets fuel means what"?)
  8. if flooding, i unplug the fuel pump relay and start car with test fuel if it runs for 3 seconds and stops, that is a PASS condition so but if not 1, to 7 above was skipped. lets say its flooding
  9. if flooding did you try cranking per opr guide wide open throttle? this CUTS all fuel and clears all flooding on all gas engines. and for sure all EFI. gas engines.
  10. my guess is its running now. right? if here?
  11. if not, check fuel pressure per the fsm cranking, and the MAP sensor. out put voltage key on, and cranking. and post that.
  12. good luck.

get the engine to run on test fuel first. this saves big time labor
down time, and wasted parts , guessed at)

doing a real tuneup , is not ever a waste.
a tuned up engine pays back in lower gas costs. big time.
fuel is expensive.

'88 Mazda 323 cranks, but won't start.


I wouldn't flood one cylinder and expect it to start. Try using a small amount of starting fluid in the air filter to confirm your plug wires are installed and working correctly.

Check for spark at the sparkplug, to see if everything in the dist. is working right. And check the injector harness for something being pulled loose when the wires were jerked out.

Turning fast generally points to a failed timing chain. Check engine compression and that distributor turns without stuttering while it's cranking.
If that checks out, and there is no spark, check the ignition module and wiring on the pickup coil under the plate in the distributor. There is no valid test on module...If everything appears normal, just replace it.

Could be a problem with the crank sensor which tells the engine ecu when to fire the spark plugs, common fault. Try holding accellerator pedal to the floor while starting, can flood with fuel, was a modification on some models to reduce fuel flow a while back.

Engine keeps flooding itself, and wont start when warm


leaky fuel injectors or a bad fuel pressure regulator could be the cause. check the fuel pressure. should be 3.0 to 3.5 bar.

1988 jeep wrangler will not start


If you did check out all the ignition system and switch and everything is fine on that side, the only thing left i can see would be a faulty body ground, preventing the engine from grounding and preventing the plugs from sparking since the current has nowhere to go since it's not grounded. So check all the body grounds in that area and check for rust, or anything that could cause a faulty ground, clean it all up and try again. If it was rust, might i suggest the use of Dielectric grease, which will prevent rust from forming, but let the current flow through. Basically it's the same white grease they give you when you buy a set of new spark plug wires.

Problem with '95 BMW 325i not starting


I had this problem in my shop and its been a Crank sensor and on one occasion it was a fuel pump relay that was bad. Most like its a the cranks sensor that's bad NOT the fuel pump relay but check both. To check see what missing when vehicle doesn't start or shuts off . If there is NO gas its the relay. If there is NO spark its the cranks sensor. Good Luck and contact if you need more help. Thanks for using FIX YA
