ok, the other day i was driving my 86 rx7 and it started bucking. i took it home and turned it off. the next morning i tried to start it and i wouldnt turn over. i changed the spark plugs and it still wouldnt turn over. i have no idea what is wrong, can anyone help?

 

have you tried push starting it ?

 

it could be flooded... try unflooding it

 

You need to do a compression test and see if the plugs are firing and make sure its getting gas Inspect and make sure no loose hoses or anything And also try push starting just dont push too far

 

When was the last full tuneup? When were you injectors cleaned last? Are there any cracks in the plastic intake tubing behind the airbox? Is the air intake manifold ok? How many miles are on the exaust system? Are you sill running all 3 catalytic converters?

 

How do i unflood it? I hope my compression is good, cuz i just put in a j-spec engine about a month ago and it has been running right until just the other day, the car was running rich in gas, could that be the problem? I know my starter is good, should i still try to push start it?

 

I still do have all three catalytic converters, last tune-up? i did oil and plugs as schedule. i have 109,000 miles on the car, but maybe about 1000 miles on the engine i put in. i have never gotten the injectors cleaned.

 

To unflood unplug the egi inj. relay in the fuse box under the hood and crank it for about 15 sec. then put the relay back in and start the car

That has common starting probs covered.

The cats are most likely clogged or close to it. After you get it running right, I'd recommend at least a downpipe and only 1 performance catalytic converter.

 

im gonna do some of things suggested tomorrow....hopefully it will work out

 

ok, ive tried everything to unflood the engine and bought new plugs....nothing has worked for me. can anyone help me?

thanx for the replies everyone

 

so the fuse trick didn't work? Are you able to roll/pull start it?

 

Was it bucking really really bad the last time you drove it? Did you notice the guages doing funny things? If so, check your grounds and ignition wires under the dash.

p.s., my old 86 did this now and then for some reason. It usually happened after it rained, so look for a short or bad connection somewhere.

 

the fuse trick did not work for me. the gauges werent acting stupid when it bucked, but im sure there is something seriously wrong because it still wont start and i bought new plugs and new wires. Help, Help!!

 

ok, i got my car started using one of the unflooding methods. But i have another problem now. The car has no power, almost as if I was running on one rotor. Also my exhaust is shaking very badly......any ideas anyone?
