Alright I got my n/a block rebuilt and put all the Tii stuff back on. Its a n/a block with no emmisions, ac, cold start, egr,bac. got 3 vauum lines on it. I got it cranking over and see and hear the puffs of smoke coming from the downpipe really smooth. Its getting spark and the fuel pressure is reading around 40 psi. I tried all the unflooding procedures out there and it just wont spark up. no pressence of wanting to start. I had MMO in the engine for acouple of days to soak the seals real nice but it seems as if the plugs are fouled, but when i take them out and clean them i can leave them on the side and watch the spark on the plugs. I don't really see anything else to do except maybe try to see if it will start by pulling it in gear. Trying that later today. Any help is apreciated.

And the AFM is plugged in along with other necessary components. The only code is the TPS but thats been there for so long.

I had this problem a couple weeks ago. Mine plugs were brand new and seemed to spark out of the block but didnt once I put them in (or the spark wasnt hot enough). The engine had been running fine before that and then they randomly stopped working.

Buy new plugs and try them. It worked for me. It fired up on the 1st try after that. Out of curiosity what colour does the metal on your plugs look like? Not just the part in the engine but the metal on the plug as a whole? THe ones I had in were kindof the metal with the 'yellow' or gasoline tinge. whereas the new one were just a steel colour. both sets came direct from the dealer.

To others out there, what could cause this? 4 plugs just randomly stopped working? they were working fine before that.

I know plugs can foul and they won't fire. For some reason i have to buy plugs almost every year. I have like 5 sets now. Thats what bugs me though.

towing it would be ur best bet at getting that sucker started. any car we've had, we push started it. got on the bumper and gassed the hell outa the truck and made the car launch off.

haha. Yea we are all about the push starting. The engine that blew had no compression in the rear rotor and would not start for anything, but pushing it we could keep it running with the gas floored but it didn't do to good.

So what does it mean if it will start by pushing it but wont start with the starter?

that generally means it has low compression or the injectors are dirty and need to be cleaned and calibrated.


if it hasn't started yet after being rebuilt here is a few suggestions and possible problems to get you started:

1) install a fuel cut switch, in case it is just flooding due to low compression from the rebuild.
2) double and triple check that the CAS is installed right. if you aren't 100% sure on how to do it i can show you the way i install them.

Yea i got the fuel cutoff switch and it usually will fire up for a second when turned off but it doesn't do it now. I will have to check the timing again though.

So if i did get it started by pushing it would it start by itself after that? If not would that mean that it was rebuilt wrong?

usually rebuilt engines has no compression ....so if you push started and runs let it run for at least 2 hours so compression gets built up...make sure you dont have any leaks

i had similar problems starting a rebuild. if you have compression then you didn't rebuild it wrong... and it must be a fuel or spark problem.

turned out my spark plugs needed replacing/cleaning too... well that and i made SURE it wasn't flooded, restabbed the cas and tripled over all my lines and harnesses before i put the plugs in again

Well got it running by pushing it, but it was too late to keep it running and it wouldn't idle by itself so probably going to set the idle really high and then just lower it accordingly. It felt pretty strong for low compression though and was a pain to keep under 3000 rpms if you know what i mean.

Alright so i've had this car running for an hour or two and it still doesn't start by itself. It almost catches but it does like it did before. When it almost starts i hit my fuel switch and then it just floods, so i turn the swtich off and then it almost starts but nothin. Maybe just have to let it run longer. Also stutters at heavy accelerating from the tps but nothin to major. Should a compression test show anything right now or do I just have to let it run longer?

Also when its running, it idles alright and runs really nice just doesn't start by itself.

Is it possible that i got that crank angle sensor gear on backwards? It runs when pushed started but doesn't start by itself.
