Discussion:
No spark, unsure of what to try next

Hello,

I have a s50 XL I'm trying to get running. GM 4 cyclinder engine Thus far I have:
repaired the starter(needed new solenoid)
replaced plugs, wires, distributor cap, rotor, coil, and ignition module.

Still no spark checking with an inline tester.

Does anyone have any other ideas on something I can try?

s/n is B187V01404L

Showing items 1 - 5 of 5 results.
It was the sensing coil. Now I have spark but the timing is off. Next I'm going to get the timing right and then hopefully I'll be up and running.

Ok so there was voltage at the ignition coil, 12v.. so checked the tach wire, with a test light while turning over and it stayed solid. I think that since the ignition module is new, the sensing coil is bad. I guess it could also be a bad module, but I would hope not.. I literally opened the package, put on the grease, put it in place screwed it in and plugged it in... I would hope it's not bad.

I couldnt find the oil pressure sensor... Just a temp sensor.and a sensor wire on the water pump..
When I pulled the dist cap again and felt the distributor shaft, the top of it(with the rotor off, the disc that spins between the poles) had about 20 degrees of play in it without twisting the shaft.. is that normal? I think that I might just get a whole new distributor if I can find the part number for it...

Is that something that I might be able to get from Napa? Thanks in advance for any help.

Thanks for the suggestions. I will check that out tonight after it cools off, I haven't been able to work on it for a couple of days.

have you checked the oil pressure sender?
sometimes they run ignition power through that just in case the engine looses oil pressure to keep from trashing the engine.
