240 crank but no start

brundle · 10-29-2021, 03:28 AM

hi!
1989 volvo 240. last week, my car sorta sputter to life when i turned it over. until eventually there was no life. i deduced it’s was the intank fuel pump. i did the fuse jumper test and couldn’t hear it so i replaced it tonight. I go to start the car and it just cranks, and cranks, and cranks, but doesn’t turn over.. I can hear both pumps working, and i hadnt had any other issues, so what am i missing? I checked the FP relay and it clicks just fine, tried with MAF unplugged, no luck, checked fuses(even the engine bay one), they are fine. Really a bit frustrated and would like to solve this. Please help!

Have you checked for spark, to ensure the ignition system is working?

I check with a timing light: if it flashes like it should while cranking then it's almost certainly a fuel issue.

Is fuel reaching the fuel injectors?

I believe that you can disconnect the fuel hose nearest the fuel rail to see if there's fuel getting there. Definitely check spark.

fuel is going to the pump for sure(took off the sending hose and fuel came out) I didnt have tools to check for spark last night but will be checking today. If no spark, what are the next steps? its a yellow label ECU

Step one on an unknown no-start is a squirt of starter fluid.

Starts: ignition good

Then chase fuel.

There have been numerous reported cases of new lift pumps being wired backward.

UPDATE: Possibly just air in the fuel lines as I was able to get him to turn over after about 15 tries and have been driving ok since then.

Don't forget to hold the hose over the oil fill cap so you don't spill any gas on the ground

Checking for spark requires one hand with enough strength to pull a plug wire off, pretty easy tools to come by

Glad you got it figured out, normally priming the pump a dozen times or jumping the fuses for a bit helps avoid excessive cranking after changing the pump
