Starting the car?

Ever had this before but I have to crank it over 3 times before it starts. I turn the key and just turns over but no start. Turn key off and do it again and nothing. Turn key of and then it starts right up. Almost sounds like its getting no fuel. It's a 86 fuel injected. Fuel pump turns on. Should be an easy fix.

Well then I'd go through all the lil tuneup stuff. Then it'll be easier to see if it's a real issue or just a lil tlc needed..

I agree. Been slowly doing that every night. Thinking its something else though. Just cranks over fast twice and then the third time catches. Nothing major. Thanks for your input.

I would throw some fuel additive in it also. Maybe the lines are bleeding off fast. But I would do like stevey said and give her a good tuneup. That will probably do the trick.

When that happens it usually means that the check valve in the fuel pump is stuck or bad.
As the guys said, try some fuel additive/cleaner and see if that helps. If not the only alternative is to replace the fuel pump.

Well I added fuel stabilizer ad injector cleaner today. We'll see how that works. Thanks for all your info. Hope I don't have to replace my fuel pump anytime soon.

Well the fuel stabilizer didn't work. Ran it through on full take of gas and half way through my 2nd tank. Going to put a new fuel filter in soon because I bet it's never been change. Even though that won't help. Just making me mad and thinking it maybe be more then a fuel pump?

You'd be surprised an old clogged fuel filter will definitely cause major fuel issues. And being so cheap is something you should definitely do regardless!.

It will help your fuel flow, but it won't do anything for your problem. It's fuel pump replacement time.

Well I think I fixed the problem. Check my timing last night and it was at 10 and I jumped it to 12 where I had it set before. Start right up so far. What is a good set time with a mild cam. I see ppl going 14 to 16. 16 seems high.

i run 16, and im currently running a bit lean. and i have no detonation. but i wouldnt recommend going that high. i think the reason i can is because my heads, and my setup isnt close to the norm.

i would stick to 12. you can possibly run 14 but will need 93 octane. and even then still listen for detonation/pinging.

Okay. Was planning on running 12 but trying 14 just to see how it works.

I'm just happy it's running right and don't have to change the fuel pump.

like i said. becareful. once you go 14* and make sure you are running 93. to check for pinging, you need to load the engine. this can be done by putting it in 4th gear and going about 20-25 mph and hitting the accelerator kinda hard. this will load the engine, when pinging will most likely occur.

im still curious why it was hard starting at 10*. this is the factory setting and shouldnt have affected starting. maybe you have a weak coil also?

I will add when I went a touch too high 15* on my timing the pinging was only present above 4k- with 93 gas. I will add my local gas station is suspect.

If it is hard to start at 10* going higher will/should make it harder to start. Meaning like said above there may be another issues and advancing past 10* will make it harder to troubleshoot the underlying issue.

i agree. i would probably do a little troubleshooting first. i would suspect weak spark. then next fuel pressure.

i went to 16* and never noticed a bit of pinging. then i hooked my wideband up and notice i had almost 17:1 a/f ratio. so between those 2 things i dont know how i could get away with so much timing. but i think the trickflows fancy combustion chambers help. and maybe the full msd setup might help to. idk but i was thinking about(after i get the a/f tamed) bumping it up some more, just to see what i can get.
