Stoffregen Motorsports Posted October 27, 2014 Report Share Posted October 27, 2014 Low fuel pressure/flow Bad TPS Dirty injectors Clogged fuel filter Could be many things, but I would check those first. Quote Link to comment
mhub91 Posted October 27, 2014 Report Share Posted October 27, 2014 any chance the firing order is wrong? sounds stupid, but it's totally possible. I thought the distributor went one way, but went the other. easyiest way to check is to pull one spark wire from the distributor and see if it bogs or dies down. if the idle is NOT affected by pulling a wire you'll know that's where the problem is. mine would idle and slightly rev, but trying to move it would die.

DatsunSwag22 Posted October 27, 2014 Author Report Share Posted October 27, 2014 which is that?? Throdle position senser Quote Link to comment
paradime Posted October 27, 2014 Report Share Posted October 27, 2014 On the throttle (misspelled before) body. It sits at the mouth of the intake manifold. You'll see a wire plugged into it. If it has issues it will be sending wrong, or no information to the ECU when you rev the motor. If you don't have a consult port device, search online and you'll find a diagnostic procedure to text it with a multimeter. Unplug the wire and check resistance between the #1 and #2 terminals. Move the throttle by hand and see if the resistance changes. If so it's good. Quote Link to comment
mhub91 Posted October 27, 2014 Report Share Posted October 27, 2014 To be totally honest, and I'm speaking from experience, KA doesn't usually have TPS issues. Wouldn't waste your time with that until you diag al the simple stuff. Let's start off by checking and Check Engine codes. Go to your ECU. Look on the side where a green and red LED are. See that little screw thing? Turn your ignition to "key on engine off" nowrotate that screw fully clockwise. Wait 2 seconds, rotate fully counter clock wise. The light will start blinking. Count the blinks. One long --- followed by one short - is code 11 Ie., flashes : --- --- --- - - - - - ^ code "35" Please let me know what codes are there. If you are getting a code "35" that is code for "OK". Start here first, and I'm willing to help. Quote Link to comment
paradime Posted October 27, 2014 Report Share Posted October 27, 2014 Listen to the KA guy for sure. I know SRs. Best of luck. 1 Quote Link to comment

datzenmike Posted October 28, 2014 Report Share Posted October 28, 2014 If someone else did the swap I assume it is still EFI and not converted to carburetor? Quote Link to comment
mhub91 Posted October 28, 2014 Report Share Posted October 28, 2014 He's checking codes, my guess is that it's EFI. .....If not, he'll be searching for codes for a while! EDIT: Oh god, he HAS been gone a while! Quote Link to comment
datzenmike Posted October 28, 2014 Report Share Posted October 28, 2014 Maybe it's taking so long because there is no ECU to find??? Quote Link to comment
datzenmike Posted October 28, 2014 Report Share Posted October 28, 2014 The truck engine almost looks like it has a carb on it. FarmerJoe bolted a plate on the intake with a weber. Quote Link to comment

HRH Posted October 28, 2014 Report Share Posted October 28, 2014 I think it's code "55" for the blinky lights on the '93 D21 ecu, isn't it? Quote Link to comment
