Okay, I confirmed that I got fuel, air, and spark. I go to start it, cranks but not catching and sounds like it's flooded so I deflood and add ATF but same results. My motor shakes like crazy too when it almost is catching. Compression is great and fuel is getting into motor. Could it be the CAS??? TPS???? I give it full throttle and that's the only time it wants to catch. Im really stumped here, please help.

 

Have you tried a rolling pop start? If not try that. I have had the same thing happen to my car... Been So flodded that i took out the plugs turned it over, took out the injector fuse turned it over, let it sit for a few hours nothing.... I tried roll starting it and it worked! engine ran extremely shitty for a few minutes.. After that A ok~

 

See at first the motor was getting no fuel. So I had my 800cc injectors put to primary rail and now it seems like too much fuel. Gonna swap it again and see. Could be bad 550cc injectors. Thanks for the suggestion though.

 

Injectors are working. It seems like there is too much fuel going into motor because it almost starts then back to just cranking. AAAAAHHHHHHH...this is giving me a headache...now my starter is bad after so many deflood attempts.

 

Happens with my buddy too. Checked everything. except removing the fuse and such, and didnt pop the clutch , itd be too big of a hassle in the city and such... may have to do that stuff though...

Isnt it a pain though lol.. Looking at ur car for like hours, and still stumped lol. Then doing the same stuff over and over haha. Dont worry, happened to me today, but gonna have to try that stuff tommarow ...

 

LOL...yeah man it really sucks. The wierd thing is that when I started her up for the first time it started but had to shut it off due to a coolant leak. I know for a fact now that I have a major flooded engine but cant do nothing about it till I get the starter rebuilt. And even when I get the starter in I just know theres gonna be more PITA stuff to figure out.

 

Haha, yeah man. I feel your pain hah

 

I had the exact same problem, drove me crazy for a week. Finally fixed it by adjusting the TPS.

 

I was also playing with the tps, like unpluging it when starting and it seemed to start better. So I know I gotta adjust it and see the results.

This is just too wierd. After deflooding it, put a ton of ATF in lower spark holes, it cranks, almost starts, then floods and back to cranking. This is a low mile rebuild too about 1000 miles on it, so the compression has to be good and also sounds like it too. Strong even pulses. Gonna try to roll start it sometime this week and will post back soon but till then keep the suggestions and experiences coming. Thanks for all the replys so far.
