It sound like you have an injector problem. the injectors may not be giving the engine enopuph gas to run. so the engine will stall. the fuel pump with shut down as a saftey measure.
have you injectors cleaned and checked for consitancy.

2000 mitsubishi diamante has spark has fuel up to the injectors and power but wont start.


At injector's, need to check if you have ground pulsation, to check, connect test light on pos (+) battery terminal, now your set to check ground, at injector harness, probe wire's, while some one cranks engine, look for pulsation, if you don't have pulsation, it will need a computer, injector pulsation is control by the computer, if no pulsation, then no fuel can get into cylinder.

E.C.M control injector pulsation, with key on check for voltage at injector harness, then reverse test light at battery and check for ground at the other wire at injector harness, crank engine ground should have pulsation if none bad E.C.M,good luck,hope this was very helpful.

1987 toyota corolla 3dr hatchback with 1.6l DOHC 16v eng. Came in with a no start. have spark and check engine light is on with key and get a code 6. TPS all checks out good. Checked wires from distributor...


A code 6 is an RPM missing signal. Your distributor coil circuit is open (or could be the coil).Check continuity with a volt meter.Check the blue/yel wire and the white one for cracks or broken,and if possible trace them to the computer for continuity. This malfuntion is a code 6 BUT car should start even so. Now to the injectors:check pulsating ground from computer,if not check wiring,if they are OK,try another computer.

Loss of power


Do you know how check if every cilinder is working? with the engine in idle, go to the distribuitor cap and carefully unplug one at the time, every cilinder spark plug wire,in the cilinder you dont see a diference in rpm variation, that cilinder is not working, replace spark plug, if you see spark jumping fron the distribuitor cap torch the spark plug wire, another cause to a cilinder fail could be a loss of compression in one or more cilinder

Won't crank


Hi,

I am assuming that the engine is cranking (turn over) but will not run.

Most gasoline engines would need only two (2) elements to run; fuel and ignition (spark) at the right moment. Based on your post, "not appeared to have jumped timing", it would then be assumed that the "at the right moment" (at least for the spark) is good. Next to check then would be for the presence of spark; this could be performed by removing one of the spark plugs, reconnecting the said plug to its wire, let it rest on any exposed metal and crank the engine. There should be a pulsating spark at the end, if yes then problem is most likely elsewhere, if none, then next to check (depending on the engine type) would be the:
  • high tension wires;
  • distributor;
  • distributor cap;
  • rotor;
  • ignition module;
  • ignition B+12.
If there is spark and yet would not run, then the fuel delivery to the engine has to be checked. There are two checks on the injector:
  • electrical - pulsating +12 on each of the injectors while cranking;
  • fuel spray - you need to remove all and check if each will spray fuel (while cranking). For safety reasons, pls have several disposable containers ready to catch the fuel, paper towels or rugs to wipe/clean off any spilled raw fuel. If yes, problem is elsewhere, if not and no pulsating +12 while cranking, ECM wiring or connector, if there is pulsating +12 yet no fuel spray, then defective injectors or defective high pressure pump.
In some instances, it could be the alarm/security/immobilizer acting up which prevents the engine to run.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
