Starting question
93 fd only apexi intake and hks bov
My car starts perfectly the first time. If I drive it then stop at the store then try to start again it struggles and I have to crank it a few times before it catches. I'm hopeing it's something simple like it needs plugs. Just my car is way to hot to check. So I thought is pick your guys mind. Thanks |
I was having the exact same problem. Mine starts perfect in the morning or after sitting for a few hours. Then after it is warmed up it has a hard time starting. I asked the same question and some people on here told me its probably low compression. I did a compression test with a regular compression guage and held the relief valve open. The compression was low. Meaning its coming in on a rebuild. I'd try that. Or bring it to a tuner or dealer that has a proper rotary compression tester. It sucks but your probably in for a rebuild

is it slow cranking..
Or does the engine roll over strong but refuse to start? |
It seems to be strong but just doesn't catch.

It could be leaky injectors, or a tired motor, a warm engine has less compression warm than cold, so it can be harder to start warm.
I would check compression of the engine warm first before putting money into a injector cleaning/replacement Mine did the same thing a few weeks ago, drove it for about an hour straight, went to dinner with the g/f, tried to start it and it was flooded, compression checked the front rotor a few days later with a new battery and its at 70psi, so i'm fairly positive thats why it flooded on me. But, since i put a new battery in it, it hasn't given me any issues since. starting RPMs mean ALOT with these engines |
Thanks for the tips guys. I really do appreciate everything. I'm going to so a compression check and while I have the plugs out I'll check and replace them. I guess it's possible it's the battery. I have drained it out twice on accident

I just bought a 93 FD back in June and had the same problem. The car had a strong fuel odor after shut down so I pulled the fuel rail, deleted the fuel pulsation damper ( search function is a wonderful tool on this forum), pulled injectors and got new o rings and had them flow tested. While I was in there I decided to test the solenoids on the rats nest, and ended up replacing 4 of them ( double throttle, charge relief, charge control, and egr). After all this I had no more hard starts, if you decide to replace injector o rings definitely check your solenoids while you have it all pulled out.
