Hmmm. Getting fuel and spark, just died.
Possibilities: Crank position sensor. Sends pulses to engine computer. If it dies, so does engine. Mounted near the transmission bell housing. Check plug which appears near the passenger side firewall. Plug gets corroded. Disconnect and clean all the plug contacts in that area,
Radio supressor relay. Mounted on inner fender, passenger side, above the battery. If it fails, fuel injectors die. Remove it from socket and insert a jumper wire between the two large pins (brown wire). If car starts, buy a new one. About $95 new; less on Ebay. I always carry a spare.
Where do you have spark? Sometimes the high voltage lead from the coil to the distributor goes bad. Disconnect it and hold it near a ground.
Do the same with a spark plug lead.

    Another brilliant idea from a 20-year Volvo owner: A broken timing belt would totally shut down the engine. The 740 has a failsafe feature, If the belt breaks no damage will occur to valves, etc.

Pickup coil?


sounds like you need to clean out the carb. or you have the wrong gap on the spark plugs. having to jump start it i would start with the spark plugs gap. gap open to much will take a bit of starting. and when engine is at running temp. it use less fuel and the spark plug gap gets bigger. until there is no spark or not a good one to keep engine running.

While drviing down freeway today the 2.5 ltr engine died and will crank but will not start. one month ago it was backfireing in intake and dieing on freeway and i thought i had bad gasoline it fixit


you need three main conponents for the engine to run,fuel,spark,compression . first have someone to crank the motor and put the spark plug lead of the plug and hold it near the block and if there is spark it will jump a inch or so, check the fuel filter , hold the fuel line clear of electirical and heat, crank engine , fuel will flow, when engine is running but running rough as a miss fire disconnect plug lead one at a time till you find missing cylinder

P/u died and now won't start, where should i start looking?


Assuming that your engine rotates when you try to start, you would want to start by checking the basic components for cobustion engines. Air, Fuel, Spark. Make sure that you do not have anything obstruction the flow of air. Check to see if you are getting fuel to the injectors. Check to see if your distributor is providing spark to the plugs. The most common reasons for running engines to die and not restart are generally associated to mechanical devices malufunctioning or jumped timing. Try to eliminate these possibilities as well as checking for blown fuses before "sensor searching".

My Madza died while driving down th highway, felt


If you dont have much money, guessing what parts to change gets expensive. First, you need to verify if it has fuel pressure and spark, that will lead you in the direction to start looking for the problem. Pull 1 spark plug wire off and see if it will jump a 1/2" gap, If so, thats good. If no spark, make sure the cam is turning, you may have a broken timing belt.

1990 geo wont start!


With the limited information given, I will have to assume that you are certain that the injector/injectors are "firing" properly. You said you are getting fire, so I will assume that you have definitely found a spark. The only things needed to make an engine run are air, fuel, and fire. You just have to have everything in the right order. It sounds as if you have a timing belt that may have been a little to loose, and has now jumped a few teeth, causing the valves to open and close at the wrong times. This is one of the only things that could have happened, and still allow you to have spark, as the timing belt runs the camshaft, which runs the distributor. The last thing that I could think of would be contaminated fuel, or low fuel pressure.....You would have fuel, maybe not enough, but you would have fuel. First thing I would check, would be the ignition timing, just to make sure the belt has not jumped time.
