    I also have a 91 samuri. It just shut off, no warning. Injector not putting out fuel. All other functions working. Some blogs indicate the ECM (engine computer) may be bad.

Check ECM (engine computer) located under glove box. Injector circuit output probably dead. Replace ECM. Go to Searchparts.com for best price.

No injector pulse


what vehicle? injector pulse controlled by computer. the computer recieves a pulse from crank angle sensor, or distributor pick up, etc.
then controls injector pulse. Mass air flow on some vehicles determines spray pattern

Ran out of gas. Put gas in but will not start. Had fuel pump checked ok. Had fuel filter replaced. Checked if fuel was getting to injectors ok. Getting spark. Will try to start if starting fluid sprayed...


Check your fuel pressure regulator. Remove the vacuum line attached to it and hook a fuel pressure gauge to the schrader valve on the fuel input line. The gauge should read at least 40 PSI, probably closer to 50-60 or more.

If it's lower than that, you're not getting enough fuel to the engine. It may also be stuck shut, meaning that you're putting in too much fuel.

If you find that the exhaust smells of fuel after cranking for awhile, there's a good chance that you're flooding out due to a faulty FPR.

Check if you are getting spark in your plugs. if there's a spark, check the fuel pressure.Your pump might not be delivering the required pressure and volume.
If there's no spark, check your ignition system components.

Look at the timing belt and make sure it is on and tight. Then maybe pull the distributor and make sure it isn't bad

Check for fuses/power/ground to the engine computer (or injector drive computer) whatever the case is.

Spark, fuel pump, and starter all are independant of the fuel injection computer.

Either the computer itself has gone bad, or it is not receiving power or ground, or wiring to the injectors might be bad...

No start


if it runs on starting fluid its a fuel problem.. check fuel pressure even if its a couple of pounds off, the vehicle will not run. but using starting fluid may give you the extra poundage you need to make it run . also check vacuum hose at pressure regulator on fuel rail
