Lunacy Posted April 25, 2017 Share Posted April 25, 2017 Hi guysI apologise in advance for the long winded please help post, but am out of ideas with this.I recently acquired an 88 fxgt corolla with a bigport tvis 4age engine.It had been overheated, with a suspected blown headgasket.Could still turn crank over with socket on the pulley.I replaced the rubbish radiator and re filled coolant...went to change spark plugs and noticed water in top of #2 and 3 pistons.So head came off, gasket hadn't blown between 2 and 3 but head was bent.Had it shaved flat, new bolts and head gasket - reassembled and tried it...cranks continuously but wont fire. Since then I've tried and checked the following:Cam and crank timing marks checkedNew distributor rotor, cap, plugs, wires and ht lead plus a different distributorSparks on all 4 leads with spark plug outTested coil and ignitor all okFuel pump runs when jumped at diagnostic and cor relayWon't start with engine start in intake or individual cylindersEng main relay was missing when got it but replaced Ecu board looks gd no leaking capsTPS tested okOnly thing I can find that may be odd is with the IGN on and while trying to start, all injector pins are showing 12v. Not sure what may cause this.Also after cranking with new plugs in afterwards they don't appear to have had any combustion near them but not sure if this is lack of spark in the cylinder or lack of fuel due to an injector issueCould something with tvis be a problem?Any other checks I could make or any ideas why she won't catch please let me know...it's doing my head in now!Cheers Quote Link to comment Share on other sites More sharing options...
ajg193 Posted April 25, 2017 Share Posted April 25, 2017 What are the odds that your distributor is 180 degrees out of phase? 1 Quote Link to comment Share on other sites More sharing options...
smokin'joe Posted April 25, 2017 Share Posted April 25, 2017 what are the odds you forgot to re-attach the small earth wire from firewall to head (or maybe from the turret on those ) Quote Link to comment Share on other sites More sharing options...

I lined up the dizzy with the 2 indents on the shafts with the rotor arm pointing at cylinder 1 1 hour ago, smokin'joe said: what are the odds you forgot to re-attach the small earth wire from firewall to head (or maybe from the turret on those ) Nope that was attached however it's got alot of broken strands and is in pretty poor condition so I'll replace that tomorrow Could that possibly stop it from firing?

piazzanoob Posted April 25, 2017 Share Posted April 25, 2017 while cranking get a testlight and hook up to battery and place into one of the injector plugs this will tell you if you have an injector pulse or not Quote Link to comment Share on other sites More sharing options...
8ball Posted April 25, 2017 Share Posted April 25, 2017 Has it ever started since you've owned it? Hasn't got a fuel cut anti-theft on it? Kill switch etc etc. Quote Link to comment Share on other sites More sharing options...

Kill switch etc etc. Nope hasn't run for a couple of years and definitely not since I've had it. No alarm but havnt had a gd look for a kill switch...Wil do that today too thanks Quote Link to comment Share on other sites More sharing options...
Lunacy Posted April 25, 2017 Author Share Posted April 25, 2017 Could it be the 2 year old plus fuel in it? Quote Link to comment Share on other sites More sharing options...
8ball Posted April 26, 2017 Share Posted April 26, 2017 You're just trying to start it as it sat? Definitely. Fresh fuel and fuel filter will go a ways to helping it run. 1 Quote Link to comment Share on other sites More sharing options...
ajg193 Posted April 26, 2017 Share Posted April 26, 2017 Engine starter fluid would make it do stuff though. I reckon either the distributor is way out of time or the cams are way out of time. Quote Link to comment Share on other sites More sharing options...

Yup should do something but when I went today I found I had no spark...so have a funny feeling the spark I did have was weak and coil was on the way out. Have a new coil arriving tomoro morning so fingers crossed. Quote Link to comment Share on other sites More sharing options...
ajg193 Posted April 26, 2017 Share Posted April 26, 2017 Could possibly be the transistor module for the coil Quote Link to comment Share on other sites More sharing options...

Lunacy Posted April 27, 2017 Author Share Posted April 27, 2017 OK so today I replaced the coil and now have spark on the ht lead and on an earthen spark plug onto manifold. Still no start though even spraying engine start into intake. Had no check engine light on turning ignition on either so pulled the cluster and found the bulb was blown. Replaced that and found it was showing code 3 Found the following on the net for that code. 3 - Ignition. No IGF signal to ECU for 4 consecutive IGT signal during engine running - Open/short in IGF/IGT signal from igniter to ECU - Igniter malfunction - ECU Would I be right in thinking either the ecu or igniter is faulty? Wierd I get spark though if I earth the ht lead or a plug on a lead... Any thoughts or ideas??? Quote Link to comment Share on other sites More sharing options...
ajg193 Posted April 27, 2017 Share Posted April 27, 2017 Clear the diagnostic codes and then check again, could be an older fault? Quote Link to comment Share on other sites More sharing options...
Ranter Posted April 27, 2017 Share Posted April 27, 2017 As an aside clean or change the spark plugs, all that cranking and no fire equals fouled. 3 Quote Link to comment Share on other sites More sharing options...
Lunacy Posted April 27, 2017 Author Share Posted April 27, 2017 Cleared the codes overnight and it's stil throwing code 3. Have had new plugs in the whole time and def no sign of fouling at all on them as i don't think there has been any combustion at all even with ether down the holes. Somehow spark is ok while plug sits on manifold but as soon as plug is back in engine seem to have none...Bloody odd Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted April 27, 2017 Share Posted April 27, 2017 have you done a compression test on this since head going back on? 1 Quote Link to comment Share on other sites More sharing options...
