Hello, I have a 1990 Nissan D21 2.4L Manual 4x4 Hardbody
the other week, I had replaced an alternator noticing my battery wasn’t getting a charge, as my accessories weren’t working, the alternator was pretty bad but that wasn’t the problem, I had come to find out it was a fuse link next to the Battery Terminal. I replaced spark plugs and wires during this time too
Everything seemed fine except I had my Alternator on too loose, riding wrong on the fan barring
my car overheated on the highway, white smoke came out as I made it to an off ramp a couple miles ahead of me.
I’ve replaced the radiator
now the car turns over but there isn’t spark as I’ve sprayed starter ether to try to get it to run.
I’m replacing the Air Filter today, but I’m wondering what else I should look over before I start taking the head off and what I should be looking for if I’m going to be replacing the head gasket
any support or advice is loved and appreciated
Check the fuel pump. You might not be hearing a buzz sound when the key is in the on position. You might also want to check the fuel filter.
Ya as said above crank it over with a plug out on a plug wire touching ground to check for spark. Otherwise if you saw whit smoke you definitely need to pressure test the cooling system to check for head gasket failure. If it’s bad enough and wetting the plugs that could be causing it to appear to have no spark when sprayed
Pull a spark plug wire off one of the plugs and hold it near the block while someone tries to start the truck. If there is indeed no spark, check the distributor cap and rotor. If they are good, but not getting voltage, you need to do some circuit testing to find out where the problem is. If you can get it running, you can test for a blown head gasket with a test kit you use with your coolant. Scotty has videos on that. By the way, if you are getting spark but it won't begin to over, it could well be your fuel pump or your timing.
begin to "turn" over, meant to say
