SOURCE: 1985 Volvo 240 no fuel no spark

well first the fuel pump relay is bad, that is easily replaced. next you have no spark. the first thing you do is take the cap off the distributerand crank the engine. if it spins that tell syou thyat at least the tang or gear on the shaft of the distributor is ok and not broken. next thing is remove the #1 plug and use a 1/4 drive extension 6" long and turn the crank by hand until the #1 cylinder is top dead center(put the extension in the hole of head where the plug was and you should feel the top of the piston also make sure you can feel the top of the piston with half the extension this way you don't drop it in the cylinder with the piston at TDC(top dead center) the rotor of the distributor should be pointed at the #1 firing position. IF it does not that means your timing is off and you need to retime it by taking off timing cover and either replacing the belt/chain or gears. now if you do not have a distributor and you have a coil pack there could be only 2 things that won't give spark. either a bad coil or your altenater is bad(the battery is responsible for starting not running the vehicle like alot of people assume. the altenator energizes the coil which inturngives spark. hope this helps you please rate this thanks

check your crank angle sensor when they go bad you will get no spark.at first when they go bad it will be intermittent.its a heat related problem,when the car warms up the sensor will cause a open circuite,then when it cools down it will start again.remove it from the car and hook your volt meter to ohms and place the leads on the end of the sensor it will show continuity,while the meter is on hit the sensor with a heat gun till warm if bad it will show an open loop when hot if so replace.

Hello
A common cause of this problem is a defective fuel pump check valve, hook up a fuel pressure gauge to the fuel rail test port and verify there are no leaks, start the engine and let it run until the fuel pressure is steady, then shut it off the fuel pressure should remain within 5 PSI of the running reading, if not then the fuel pumps built in check valve is defective. The reason this causes hard starting is the fuel drains out of the line due to the defective check valve, when you start you get air to the injectors for a second, this causes rough running and a stall in some cases, 2nd restart in most cases is ok. Do the leak down test and let me know the test results.

Runs a few minutes, then dies and will not start again until the engine cools down - 1 hour or so.


There are a few things effected by heat that could be causing this. Crankshaft position sensor (if your car is equipped since Mercedes started using them sometime around 1991-1992), Fuel pump relay, fuel pump itself, ignition coil (s) and ignition control module (EZL). The only way to narrow down which one it is, is to diagnose the problem WHILE its not starting, so test for fuel and spark during those times and narrow it back from there.

1980 mercedes v8 gas, fuel problem running?


If the car has a carb (not fuel injected) try removing the air filter cover and pouring a small amount of gas down the carb . Now try and start it aND see if it will start. If it starts and runs for a 10-30 seconds and then dies, it is a fuel delivery problem. Car should start if you add gas unless the car is being flooded out. I can't really help you with a fuel injection system except to suggest to replace the fuel filter and see what happens. Just remember you need spark, fuel and air to make combustion. YOu say the car fires so you have spark. I would focus on the fuel delivery.

Old j reg mercedes 230te wont start


Check Injectors spraying Fuel when you start. Fuel pump prime because you hear the pump. IF pump is weak, then your Fuel distributor doesn't have correct pressure to spray fuel when injectors open. Do your sparks plug wet after trying several times. If they are dry then you don't have fuel. Replace injectors If they are wet then you don't have correct air:gas ratio of 14.6:1. Replace Fuel distributors
