#Clover efi no signal how to

I need to find why code 42 keeps reappearing, what's the chances of a faulty ECM? Does anyone know how to test one?Īlso with timing advance I checked it under load also and when accelerating it's about 32* btdc but does go to about 36/37* btdc when reducing throttle.

Intake is fine and have replaced exhaust risers and manifolds lately plus leg was off just over a year ago and no blockages then.

It's 100% firing on all 8 as I checked and doubled checked that a couple of times. So stopped checked for codes and code 33 appeared. I disconnected the map sensor harness today and it ran rough, quite a bit of white/grey smoke. The fuel pressure was with ignition on as I was told this would be enough, spray pattern from injectors seem fine. However if I put a 12v test light on ckt 424 is should drop below 1000 ohms, both of my new modules don't they increase very slightly! My old module would decrease from 5000 to roughly 2000 ohmsĭoes anyone knows what values you are getting, testing resistance on ckt 423 to ground then attaching test light to ckt 424 and reading value again?

When checking the ohms across the IC module I get about 9000 ohms, manual asks if it's above 3000 ohms so that fine. I go through the test procedure as in the mercruiser service manual!! And it keeps pointing to the module but it can't be. Haven't been on for a few days as it was raining and only just got another new ignition module. Next boat is going to be twin engine so I can just swap bits over!! I seem to be getting 38* btdc by 2500 rpm which I know is too high which makes me think something's wrong with ignition module? As base timing is set at 8* btdc, idle is roughly 12* btdc but does vary until warm. I have a LED and jumper cable to read, reset codes and set timing but not a proper scan tool.Ĭan some point me in the direction of timing curve for delco ignition as I can only see TB systems. I took the boat for a spin to check a few things, it's definitely firing on all 8 and getting about 3600 rpm. Checked the KS module again today with another ignition module I have and it's now getting 10v however I tried tapping engine and also repeatedly touching KS harness with test light but never noticed any fluctuation in rpm. Are the ignition module and knock module linked or could I have a bad knock module also?Īlso timing was at 12/13* BTDC so I've now put that at 8* btdcĪny input would be appreciated, can't seem to find anyone with same problem which is a bit strange!!Ĭhecked the grounds, all fine but cleaned anyway, power into the KS module is 12v. So I checked knock module today following diagnostic in manual and where I should be getting 8-10 volts I'm only getting roughly 4v. I checked for codes and got 42 so went through the diagnostic cheks in the manual, I wasn't getting the right ohms on the ignition module so got a new one but it hasn't helped and actually I seem to be getting worse results so might be a bad module I don't know, got another module on the way. No real power at all, in fact since I've had the boat it's never been great.Ĭompression is good 170-180 psi, new fuel and pressure is 30psi, so it's not a fuel problem. So this season, end of last I couldn't get WOT and now only getting 3200 revs roughly, cant even get up on plane really. I've got a 1995 mercruiser 5.7 efi s/n 0F431832, Delco est ignition I've posted on another site but thought I'd see what you guys think.
