got the timing right? I spent forever getting my car to start after taking out the distributor.

Are you sure your motor was at TDC when you replaced the cams & dist. I f'd up and had mine at BDC . I just put it to TDC, got my alignment marks right on the timing chain and dist. and it started right up then I adjusted the timing. BTW mine sounded just like that at BDC .

yeah we made sure it was at TDC, we may have put a rotisserie skewer in plug one but it got the job done.

I don't think its the cam timing. I would check the ignition timing first and check for spark, Did you also check to see if you injectors are spraying or even getting the pulsed ground from the ECU?

Fuel, air spark.... make sure all 3 are making it to the combustion chamber. If they are and you get nothing check compression because there is a chance your new cams could be off. If nothing then check your sensor wiring and PCM

i know im getting fule and i know im getting spark and there isn't any reason why it shouldn't be getting air... i already flooded the engine.we're thinkin starter

I just changed my timing chain. Took forever and was such a pain in the ***. Anyways, After installing everything back together and trying to start the car, it pretty much does the same as your car...... I have no idea what it could be, but im guessing it has somethign to do with spark plugs because I just bought some and installed them. They should be working fine but I will have to take another look at them. Im almost positive that everything was at TDC when I installed everything back together...... Let me know if you come up with anything on yours.

Also, how would I be able to check if my spark plugs are working? im pretty sure injectors are working.

Could my timing have anything to do with it not being able to start? and how would I go about figuring that out?

hahaha, seriously.

Found these on Nico. Im going to try changing the TDC stroke today to see what happens.

yeah my starter is shot.

and as for your spark plugs you can get a spark tester at autozone. oh and make sure your cams are in the right position, or else you won't have enough pressure, and since you've been trying to start it so much you probably flooded your engine.

I dont mean to thread steal but, im still having the same problem

I took out the spark plugs over night and waited for the gas inside the engine to evaporate, then I switched the rotor inside the distributor cap around to the oposite side as to switch which stroke it was on. Still nothing and it actually sounded weaker than before. I switched it back and made sure all my plugs were inserted and called it a night.

How did you go about checking your starter?

Advanced auto parts has a bench tester. you might have a hard time getting the starter out.

Also get a really long srew driver and take out the #1 spark plug, then put the srcewdriver where the spark plug was, and manually crank the engine with 27mm socket untill you are at TDC of the compression stroke. then adjust the distributer so its on the #1 spark plug... that might be your problem. idk its kinda hard to do with out looking at it. are your cams in the right position?

you mean THREADJACK. lol. To OP or you, I am assuming there is definetly something wrong with your timing. OP had cams installed so thats an important factor to look at.

BTW: DubsSuck, did you get your car to start after finding your starter was dead?

I have tried the screw driver in the cylinder and rotating the distributor rotor as to set it onto the second compression stroke. Either way, my car didnt start. Im thinking it might be because I probably flooded it. Im going to try it once with each stroke today and see what happens. and no, I only changed my timing chain, so I too am almost positive its my timing.

Thanks for the info guys. Really appreciated.

I just got the starter today.. and i don't have a garage so i have to wait for the weather to cooperate.. it just snowed yesterday. I'll let you know if the starter does the trick though.

ok if you put your engine at DTC of the compression stroke, your distributer at #1 and have your cams in this possition:it won't matter where the chain marks are. that should fix your timming issue

whats all this talk of flooding the engine? i thought you couldnt flood a fuel injected engine. the injectors just spray a little bit when you turn the key. correct me if im wrong but ive neeeeever flooded a fuel injected car. carb'd yes but not fuel injected

and when you try to start your car the starter is turning over isnt it? i dont see how a bad starter could keep you from starting the car unless it just plain doesnt work. have you performed a compression test? that would been the next thing i did after checking for fuel and spark

the fule pump primes the line for 5seconds when you are trying to start the car and if i doesn't start because of incorrect cam timing it is possible to flood a fuel injected engine.. im gonna tell you straight up, i've never went to school for this stuff everything i know is from experience. so if i'm wrong please correct me, but i'm telling you now i've flooded my engine.

have you checked your compression? how can you know its flooding if you cant get it to start at all? it could just have no compression. im willing to bet its not flooding but thats just my .02

found this with google.

This can be caused by many factors, but first to answer your initial question, yes it is possible to flood a fuel injected engine. Flooding of the engine usually involves a malfunction of any one component of the powertrain control system, ranging from sensors, to the engine control computer. The first thing to check will be fuel pressure coming into the engine. This can be accomplished by installing a fuel pressure gauge inline with fuel supply line going into the engine fuel rail. I would look for 35-45 psi of fuel pressure.

well its kinda hard to get your car to start if its flooded.. and to answer your question yes i did check my compression and it was a good 60 ps wayy tooo low. thats when i found out that my cams were in the wrong possition. After i timed and repossition them i took the vid and guess what there was enough compression for combustion!!hopefuly the starter will do the trick.. which btw triped the breaker at advanced during the bench test cause we were putting so much amprage through it. so yea its dead.

rotarys flood really easly, i stalled my friends rx7 once and it flooded.
