Ok i did the fix for the pulsation damper and i am pretty sure i did everything right. well my car wont start now, at all it just turns over with no attempt to even start. i tried putting carb cleaner in one of the vacume lines and in the throttle body to see if it would even attempt to start, but nothing. ive double, triple checked every connector everything that could possibly cause this and nothing.i tried taking everything apart and doing it over still nothing. so im stuck, i was wondering if maybe it has to do with my injectors, i was thinking maybe i flooded them out or something and they arent delivering the fuel. i dont know what to do and i need help??? please anyone???

 

Easy on the carb cleaner you might be flooding your engine. Don't crank it for too long you might also drain your battery. Unplug the EFI fuse and crank the car for 15 second. Plug the EFI fuse in and try starting again. Again don't put any more carb cleaner in the engine. Hope this helps.....

 

thanks twiste! uhm ill try that out, i havent used that much carb cleaner to try to start, actually i only used it once to see if it would work. but what does taking the efi fuse out do to help it? just curious i like to understand things. and the battery is good still so i know its not that, and i dont think it would be a spark problem cuz i havent messed with any of those componants and the car worked fine before i did this. but thanks ill try that out.

 

anyone else?? all help would be awsome, cuz yeah i love my car and i dont have the money to take it to some specialist. any other problems it could be? can carb cleaner ruin injectors?

 

exactly what fix did you do for the PD? did you rtv everything back together? did you break any oil injector lines? are ALL the vacuum lines hooked up (inc. 3 on front of tb, 3 on back, and the assorted boost lines and the air bypass hose (the big one)) AFM plugged in? tps plugged in?

k now that youve gone through that list, pull the egi fuse (2nd row down, 2nd one in on an s4) and crank for 10s. then replace and start... didnt work? try a teaspoon of motor oil in the plugholes.

if that doesnt work.. then.. well.. i dont know anymore .. i just dont know..

 

yes everything is plugged in, im not sure what your abbrv. were but i followed the haynes manual on how to take it off, but i replaced it with a banjo bolt from another rx-7's fuel rail. oh and my car is an n/a 87 se. and i tried the egi fues trick nothing at all. i marked all the vacume lines when i took them off so i know they are right, and all the other connectors are all back together right. the only thing i could be thinking is that somehow there is no fuel coming out of the injectors. i cleaned them off with carb cleaner could that have any affect on them?

 

replaced injector o rings? does it come close to catching? or just cranks? does the tach register 250rpm when you crank?

to check for vacuum leaks.. get starter fluid, and have an assistant spray around the motor while someone cranks. when the motor starts to catch.. bam youve got it.

im somewhat at a loss however. do you have fuel pressure coming out of the upper rail by the regulator?

 

Have you primed the fuel pump? There's a yellow connector back on the firewall near the passenger's side. With the ignition on, jumper this. You'll hear the fuel pump run, usually a loud hiss of air filtering out of the system, and then a softer steady hiss of fuel running through the fuel loop. Remember, you drained all the fuel from the system when you replaced the PD, and the fuel pump doesn't run unless the engine is cranking. It might not have pushed enough fuel up yet.

This is also a *very* smart way to look/listen/smell for leaks. Fuel spraying onto a cold engine is generally not terribly likely to ignite. Fuel spraying onto a running engine is. I like to keep a fire extinguisher handy after doing any fuel system work, just in case.

sorry this is my friends screename, uhm i did check the gromets and o rings and they all looks brand new so i didnt mess with them. but as it is the motor doesnt even try to start at all. ill try to see if i have a vacume leak. and im positive there is fuel in the system because when i took the system apart again to try to solve the problem there was fuel in the lines. im not exactly sure if i have fuel pressure on the secondary fuel rail, but when i took the system apart for the second time i did have fuel in the lines and in the rail. how can i check for to see if i have fuel pressure? i would like to thank you guys i really need help with this, im pretty confused as to why this is not working.

lol.. i had my bro hold the gas line while i cranked.. lol.

 

oh ok well thanks guys ill probably get on it tomorrow morning thanks for all your help i hope i can figure it out. goodnight

 

Your fuel lines were not put on correctly.

That was my first guess too. Classic symptoms of swapped supply and return lines.

 

well i really doubt that they are put on incorrectly, i dont see how i could mess that up.

 

Its actually really easy, especially if you've removed the rats nest.

 

i didnt remove the rats nest, i just took off what was needed to get to the PD

 

no ive noticed that there is fuel dripping off the injector on the secondary fuel rail near the fire wall.
