Hey everyone, there was a problem that occured a few weeks ago that i have not found a solution too. The car is a 88 rx7 vert N/A. The problem is that the car cranks but does not want to kick on. All I did was change the clutch and now it wont kick on. It cranks over fine and i get spark and i pulled a hose to see if i get gas and I do. I also tried the de flooding procedure and still nothing. It starts one and a million tries. or if i PUSH START it then itll kick on. I dont know whats going on and would really like my car to run again. Any pointers to where to even start.

You might have low compression. Have you checked it? You can also check pin 2I which is for the Water Thermosensor which helps to identify how much fuel is used upon starting the car. W/key to on it should measure between 2 to 3 volts for a cold engine and the voltage drops to just under .5 volts when fully warmed. And was the car acting just fine before the clutch was changed?

And what procedure did you use to deflood the engine?

i have not had the motor checked for low compression. Nor have i checked pin 21.
Before I changed out the clutch the car would turn over and start up just fine. It did run a bit rich though from the smell of it and when i gassed it there would be a slight studder in rpm. i would always assume it was the tps or someone messsed with the air to fuel settings. the fuel pump was also changed out because it was bad

And when was the fuel pump changed relative to the clutch replacement? And the starter always turns over w/key to start?

And what about the deflooding procedure used.

And each and every time you try to start the car and it won't start you will end up dumping more fuel into the engine hosings making it harder and harder to start the car. Once you share how you are deflooding the car then maybe a better method can be used.

the fuel pump was replaced first after two months of having the car, but the thing about the pump is that it was wired from a switch that was directly to battery. I replaced the pump but as for the connection i had it at least re wired to a spare fuse on the inside of the car.

then after driving it at least another 3k or so i decided to change out my clutch. which i did then the problem had occured. i knew that even before the clutch replacement i was running rich. thought it was due to air/fuel mixture and me fiddling around with some ***** to see if i could adjust it but still made no difference.

as for the de flooding procedure i followed what i read which was taking out the fuel fuse in the engine bay and cranking it but like what i said up above the fuel pump is wired to a switch any way so i would have the switch off and cranked it over. this would help and i would catch after some trys. but im still at step one which is trying to getting the car to catch on.

theres new plugs wires fuel pump starter clutch and corroded grounds were redone.

It's possible that your fuel cut switch is not working as it should such that it's a hit and miss type of thing.

Which "*****" did you mess with in an attempt to alter the afr's?

And you might want to look at the plugs to see if they are wet or not and if so take a blow dryer to them.

W/the fuel cut switch in position to stop the pump and w/key to start the wire that feeds power to the switch should have voltage does it? If it does make sure the other side does not to prove that it is working. If you flip the switch to allow power to the pump does the other wire at the switch then have voltage too?

If you spray one to two seconds worth of starter fluid into the air intake duct w/the pump in the off position can you get the car to start briefly?

it was a while since ive tried to start the car. i did take look at the plugs but they were dry. but looks like the ends are getting to be really black. i did re wire a new switch and can control the pump on and off. also i did go ahead and bought some starter fluid and BOOM car started up for a brief second.

the only thing i did not change was the fuel filter on the car. and do not have a gauge to check the pressure of the gas flow. but im assuming my pump is fine since it is recently new. any more helpful tips, your leading me the right way so far. should i replace that filter? i already pulled it

RickysFC

so i checked if my fuel filter is bad, and what things on google say is, if i can blow into the filter and there is minimal resistance then its still ok but if theres more then minimal its dirty or clogged? i felt as if it was hard to blow through filter to feel any pressure. i blew a good amount of pressure and felt only the littlest to no air. should i replace it? soubds like its clogged.

When in doubt replace it, but it seems like there really isn't much doubt if you feel like it's clogged. You can disconnect the return fuel hose and place it in a jug.

To properly deflood the car repeat the starter fluid trick two times w/the fuel pump turned off via your fuel cut switch. Then turn the switch to the on position and try to start the car in a normal fashion. If the car starts but immediately dies then jumper the Fuel Check Connector and start the car again.

And clean your plugs if you haven't yet done this.

Sorry about this late update. So the new filter was replaced. And still my car does the same issue. Now the only other thing that Ive concluded was that when me and some friends push start the car it turns on every time. the only time it wont start is when i crank her normally. not to sure could it be fuel injector, the pump maybe went bad. still searching for this unknown cause
