ok so i bought the car yesterday its a 88 no emmisions everything is blocked off by a professional its streetported also ok soo here is the problem i have plenty of spark i have fuel also but it still wont fire it just wont even attempt to fire it will just crank and not even feel like it wants to start


please help thanks

 

might alllready be flooded.

 

it cant be i cant smell fuel but its all over the plugs after i crank it ? i dont understand i cant smell the fuel but its all over the plugs after i crank it ?

 

If it was running fine before and now it won't start its flooded. If you have been trying to crank it without doing the procedure, you probably have fouled plugs and need to be cleaned off, on top of deflooding the engine. Change your oil when you get it started.

i allredy did that process and still wont fire ? any suggestions

 

Was it running before or you bought it like this?

 

i bought it like this but it did run before it was my friends it jusst ran 3 times for about 5 min each time but never moved just got up to temp

 

how long ago was this? Please give more detail about the condition of the engine, last time it was ran, last known condition of it from your friend, ect.....

I will repost the information from your OTHER SAME POST :

Be the way, did you unplug the EGI fuse and crank for about 15 seconds, clean out spark plugs, and then try again with EGI fuse back in? If this didn't work did you try a teaspoon of motor oil in the chamber after cranking for 15 seconds with egi fuse out and putting fuse back in with spark plugs clean and oil in chamber?

Make sure to keep your foot all the way down on the pedal when clearing the flood, and don't push the pedal at all when trying to crank with the fuse IN.

 

well it sat for about 4 monts in the garage and he dident touch it it has a miled street port and everthing is blocked off for the emmisions has semi new coils and new plugs and wires it ran before but it ran lean thats y i put the safcII in to richen it up it needs a timing to but it would still fire if the timing is off or attempt to

the engine has 0 miles on it just about 20mins of run time

 

Have you tried removing the egi fuse, one of the spark plugs on each rotor and cranking for 15 seconds, add teaspoon of motor oil, clean plugs, replace plugs and fuse? Make sure to have your foot all the way down on the gas pedal when deflooding without the fuse, and don't touch it at all when restarting the engine.

You probably need to build up a bit of compression using the motor oil.....

Once it starts by the way, fully warm it up and if you are going to shut it down hold the gas pedal to rev it a bit then immediately turn the key to off while still holding the pedal down to clear the pressure off the fuel lines. This will prevent flooding.....

 

i actualy did the unflodding process to day twice and still no luck the engine has good compression thats what i waz told by my uncle today who cam by to check that i usaly kno what im doing with the rotarys but this is competley confuzing me hahaha

 

Hmmm..... is your air flow meter connected? If this is not connected/detecting airflow I believe the injectors will not fire. You said you hooked up an SAFC so this might be your problem....

Also if the timing is significantly off it won't fire. You need to set the timing correctly by taking off the CAS cover, search it here.....

 

what u mean by take the cover off ? what the correct timing for the car ?

 

Nevermind

 

Beat me to it, I hate work

 

you think the gas might be fowled sence its been sitting ?

 

The timing post is here:

But like I said before, you need to build a bit of compression so try using the motor oil method I explained earlies. It might take a few tries and like RXJIM said there are times when you will have to play with the gas pedal after replacing the EGI fuse with the motor oil method if it was flooded enough.

Make sure to hold your gas pedal all the way down when you remove the EGI fuse, I have even had to crank the engine with no spark plugs to get the fuel out of the chamber, it was that bad....

I doubt for 4 months it would foul the fuel in the tank by the way....

 

allright man thanks for the help ill try it tomorow if it starts or dosent start ill let you kno ether way

 

dosent everyone hate work haha but ya ill try the unflooding method again and ill get new gas and see how it goes ill let you kno if it starts or doesnt ill let you know ether way thanks for the help man

 

Clean the connections coming from the CAS (Crank Angle Sensor) with some electronics cleaner spray (open them up first). On connection is on those wires coming out of the CAS about four inches out and the other is under the brake master cylinder.

 

Without the AFM, the injectors still should fire as your engine is turning over. my car did the exact same thing and it was my injectors werent firing (different scenario, in my case wrong injectors)
