Rough Startup
 

I have a 95 that is having problems starting. it takes several 10~15 second burst of the starter to get it to start, and when it does start, it slowly revs up, not the snapping starts I'm used to out of an lt1.

I started out when it felt like it had a miss. SO I replaced wires and plugs, wasn't sure when the previous owner had done this last and it has 175,000 on the odometer.

A few weeks later the miss is back and getting worse, now I'm losing power going uphill at slower speeds and by hill i'm talking abou tthe 15 to 20 deg climb out of my subdivision. it would go away after a while but got progressively worse. Checked the fuel pressure and the pump wasn't building more than 25 psi and would drop off when i rev the engine.

So I replaced the fuel pump and now have 35psi at idle and 45 when I start opening the throttle.

This worked great for a few days...then the car would flood at startup...so the injectors are dirty and now leaking with the extra pressure. I bought new 24lb Ford Motorsports injectors and installed them the ohter night.

So at this point I'm back to the rough start thing where it won't climb hills right away but will smooth out after a while and will run perfectly.

Then I noticed that if i'm in park/neutral and I rev it up from idle it stumbles slightly and then rev's up. Not sure what that's all about.

Also right after I start it and its doing this no power bs, it will pop back hard thru the intake, or won't rev up, to where it almsot feels like it has no timing or has been retarded?

I thought it was the coolant sensor and swapped it out last night thinking that's why the fans were coming on so late the temp gage was getting dangerously close to the red line sitting in the driveway, but later I determined that the radiator was about 1/2 gallon low on antifreeze, not sure where that went but the oil was clean, the passenger side floor is dry and there aren't any puddles of water under the car.

The only thing left if the Opti, coil, and ignition module...any suggestions.

It sounds like you have a head gasket leaking...that would explain the low coolant and sluggish running. See if you can smell it coming out the exhaust when you first start it. Pull the spark plugs and see if one looks really clean....Thats a starting point for you. Good luck

get a leakdown test done, its either the opti or blown headgasket, i was the lucky reciepient of both. check to see if there is oil in coolant or coolant in oil.

i would also scan the computer for codes or check out the o2 sensors

No codes, no water in the oil, no water coming out the exhaust.

A dying coil can cause hard starts and sluggishness under heavier loads.
