Hi i just got my new fc rx7 and it will not start it cranks almost starts but thats it. I tried the deflooding procedure many times and it actually cranked but as soon as i touched the throttle (already idling for a minute or so perfectly) it died, and i haven't been able to get it running since any ideas???? plz help me

 

Your post is very confusing because you provided contradictory information.

So you eventually did get the car started, or were you only able to crank the engine?

If the car was running but died as soon as you touched the gas, then it could be a number of things.

First check for vacuum leaks, especially large ones between the AFM and throttle body on the black intake tube.

Second, how old is the fuel?

Third, adjust the TPS. This likely will not be the cause but it won't help matters any.

Does the engine sound smooth while it's running or does it sound like a lawnmower?

 

It sounded smooth the one time i had it running, but now every time I deflood and try to start again it almost starts but thats it, then i have to deflood again to get it almost starting. Now I noticed when I deflood its got tons of gas in it just from trying too start 15 to 20 seconds. I also checked the ignition system and it is operating properly from what i can see, all coils fire, plugs are new, wires are in correct order.

 

vaccuum leak(s)? Start searching for the leak(s) and come back when you're done.

 

any ideas on how to find leaks when it will not start anymore?

 

1. open hood
2. start at the intake and check to make sure all the pipes are in good shape and CONNECTED
3. Check vaccuum lines to see if they are cracked, disconected or broken

replace anything that is broken/cracked, stiff, and try to turn it on.

 

You can cover up the TB and force compressed air into the TB. Listen for leaks. Another, more dangerous method, is spray carb cleaner around the manifolds and vac hoses and listen for a surge in the idle. This would of course require the car be running at the time....

ok i finally got it too run but it will not idle and if u press the gas more than a quarter of the way it just bogs. would the vaccuum leak cause this? another question the mafs is got lots of black gunkey stuff in it could this cause this and is it safe too use the mafs cleaner on this car?? thxs for the help guys. heres sum pics wut yall think i paid 700 for it interior is as clean as outside except drivers seat has a tear

 

Nice clean, now u need 5 lug swap, I think it may be your TPS. Not sure tho. ight man good luck

 

how many miles on the car?
maybe you need new spark plugs or aren't getting enough power to them

 

199xxx and it has new plugs. i checked the spark and it was bright bluish almost white is that good?

 

theres your problem

 

yea prolly lol

 

If the AFM is full of black goo (there seems to be a run on this lately...) then the flapper is going to get stock. You'll have to clean it out.

 

hi everyone thxs for the help got it running today by cleaning the mafs and getting the flap moving again . i alo put sum seafoam in the tank and its starting to run progressivly better. again thxs for the help
