Would like to know where is my fuel filter for 89 volvo 240DL

just above the oil filter around an inch away from the fillter housing. one single wire feed think is either a 10mm or 12mm spanner needed to remove it.

when car dies check for spark if you have no spark check the igniter and coil as well as spark plugs cap and rotor

yes it is in the tank. but you can remove the rear seat to get to the fuel pump, instead of dropping tank. (2003 to 2005) kia sorento. fuel filter is inside tank and replaced with fuel pump as an assembly.

It could be a number of things, but I don't think it is the timing. If it is there should be other signs, like after the car is shut off, does it keep trying to run and make clunking noises? Timing belts are cheap, but the labor is not...around $500 depending on the car.
I would reccommend doing a tune up...new spark-plugs.... check plug wires & coil/distributor with an OHM meter to the tolerances.
Check air filter and change the fuel filter.
This is where I would start.
Good Luck!

It is most likely that you have a hole in your vacuum hoses (check your flame trap too) or your 02 sensor is bad. i would check both. good luck:)

check timing belt

Yes this car falls under the years of the rotting wire harness,your need to give this look at first,also this car have two fuel pump relays.

Volvo is a good car. if you maintain you volvo by changing the oil on time, maybe after every month according to how you drive and changing you fuel filter, using 93 grade fuel or 89. I advice you to keep your volve. do your oil change on time don't wait until three to five months before changing your oil and don't use poor fuel (87) grade. change your tranmission oil after 18 months then your volvo is yours for life.

I just had a similar problem with my 1990 240DL and it turned out to be the fuel pressure regulator located on the forward part of the fuel rail in the engine compartment in conjunction with the mas air flow meter. Both were repalced and now the engine idles normally.

My 1990 240DL was doing the same thing and it turned out to be the fuel pressure regulator. It, unfortunatley, is a shop repair. $117 for the part and $150 for labor. It runs fine now.
