EGI fuse has to be god its pink 30 under the hood closest to the engine right? because i swapped that with another of the same amps and it didn't change anything. This car was driving down the road and just died the last time it was ran. Hasn't started since. We tried to pop start it down a big *** hill and it tried for like 1 second idles really really low and no throttle response no tach response and promply died. it was on for maybe a half second. thanks for the help

 

yeah do a compression test to make sure its not the engine.

but if it just spontaneously DIED while it was driving, it sounds like the EGI fuse somehow blew (if it wont shoot fuel or spark...)

take the upper intake off, take the primary rail off (leaving the injectors in the rail and plugged in) and crank the engine to see if fuel shoots out (obviously watch out, this is kinda dangerous)

 

b4 i even care if their is fuel im gonna work on getting the spark i know they may be related but its not the fuse. The tach wont even budge when you crank the car... the starter fluid does nothing, i need some spark

 

how about some compression? you might need that too.

 

i havn't done an offical compression check but when we pulled the plugs to do the flooded thing NO FUEL came out and when i turned the car over it shot air out the plug holes we put a lil atf in there and put the plugs back in, nothing, the car sounds like its got compression.

 

why the hell are you putting ATF in there?

and of course its gonna have compression if you put a thick liquid in there... crazy kids

 

If it has no spark, it ain't gonna start!

 

If you cant even smell fuel after cranking it then it actually sounds like the ECU either isnt getting power or isnt getting signal to start giving the motor fuel/spark. Look into it.

 

What would cause the ECu not to get power? i mean i don't know rx7's but the chances of an ecu going completly bad has to be a pretty rare occurance

 

Ive got a dumb question for ya but ive seen it happen on here before so ill ask. Does it have gas in the tank? I agree with everyone else on the coils. That sounds like the culprit to me.

 

Hahah yea i've actually ran my honda out of gas the other day and though something was wrong with it, it was bucking when i hit boost and **** :P but naw the seven has gas about a quater tank... Its got NO spark at all Whats a good way to check if its gettin fuel on these cars??

 

also is their anyway i can test the ecu myself because the mazda dealship wants 350 dollars to test mine... ALso they said they have 2 cars down their that are having the same sort of problem they have been their for a year... So i would rather not throw my money down the drain with dumbasses

 

Do your idiot lights come on when you turn the key to the ON position?

 

no

 

I would say you either burnt your wiring, killed a fuse that you haven't yet located, or killed the ECU. All you have to do is whip out a digital mutlimeter and you can easily solve most of the above!

 

OWE **** BABY WE GOT FUEL I pulled for leading plug and she was all wet :P I also checked power to the leader coil and its got 11.8 to the coil but NO spark and no tach movement

 

so im about to buy two new coils but it just seams to odd for both of them to go out at the same time, i have heard this could be my CAS anything got any insight on how i could test the crank angle sensor... its not throwing any codes

 

Does your check engine light flash at all? The coils very rarely go bad.

 

no since i have gotten this car i have never seen the check light
all the lights on the dash light up when i put the key on, put the check does not i can see where its supposed to be. and its not on ever

 

make sure the CAS is plugged in.

 

So new news::

The ground for the battery the main engine ground was just hanging in the back of the motor by the tranny not connected to anything, so i thought this was gonna fix the problem i grouded it all nice and snug to the tranny and still no spark is to be had

 

It sounds like to me joe blow mechanic had his way with this car and now your going to be the one to fix everything he mangled. But thats just how i see it from here. Whatever it is i hope its something simple.

 

Yea but its wierd because this car wasn't touched by anyone since the last time it ran....

 

Get a DMM and check voltages at the ECU, CAS, coils, etc.

 

check the 80 fuse i had the same problem kinda from what it sounds like . cause if he put the battery in wrong and it blew then it could have blown that one.
