Hi guys, recently i've been having a cranking issue that is getting gradually worse.

No longer starts at all, no spark. In the past 2 weeks ive changed the distributor, Ignition coil, dizzy cap, rotor, starter, leads and plugs.

it might be running but not very efficient. did you change the fuel filter?

its been ok on gas, nothing great but i still get about 140km per 17L at $2.16L over here. its idling fine and still accelerating like a champ. The fuel filter was done about 5 years ago lol. reckon it could be that? I would suspect running issues aswell as what i have if it was

just about not starting at all at times now

You could be loosing compression. I'd do a compression check. If it's not that then I'd like to think it's fuel related.

could low compression cause hard starts and no other problems??

try and change the little white box with a plug next to the igniter...looks like a its a mini coil relay or something...its clipped to the same bracket as the igniter and coil.

mine was bad which caused failed starts and misfires along with a bad igniter.

check and see if the fuel pressure regulator is bad. When those go bad, they cause hard starts. After running the engine pull the vacuum line out and if gas is in the vacuum line FPR is bad. [

Fuel pressure regulators are connected to the fuel rail. It should have a vacuum line going to it.

the vacuum line is the one on the top?

pulled off the top one after running and there was no fuel that i could see or smell in it. (FPR)

Have you noticed if your getting fuel into the cylinders or not? Any idea how the fuel filter is?

fuel filter was my next guess. Iti s fairly old so I should probably change it anyway. The car is idling fine so im guessing its getting sufficient fuel though. Had a hell of a time getting it going today at the supermarket

Done fuel filter today, appeared to help at first but has gone back to the way it was since, checked fpr vacuum line again and no fuel in it..

Edit: this started happening about a month or so ago at the same time as I had battery problems, have replaced the battery since but problem persists.

Just noticed when i finally do get it going it makes a sound almost like theres a belt slipping in the engine bay, ill have a listen to it tonite. im thinking maybe alternator? although the battery is charging fine.

edit: the sound is kind of like when you have the aircon on full and lights on etc like theirs a strain on the belt

Have you happened to look at the plugs after these long cranks to see if they are fouled out? Also just curious to see if your timing is spot on.

im getting CEL code 12 come up so im guessing thats the issue. but how to fix it im not really sure where to start. THe plugs are ok, were changed around 6 or 7 months ago, ill be changing them shortly though, been a bit slack on maintenance lately

Im leaning towards the distributor being faulty, there was no spark when tested yesterday but it seems to be intermittent. there is an oil leak coming from under the dizzy so im thinking there may be oil in the dizzy itself. Is there a method to test whether the distributor is faulty?
