gobby1sock Posted August 3, 2016 Share Posted August 3, 2016 Hi guys. I need some help. I've swapped and ej20g in to my Subaru pickup. I've had it running fine but recently its not started. It was running fine one day, the next day it didn't so I made a different earth for it and I started straight away. I then left it for another day. Not touched anything and it won't start. So I removed the new earth and it fired up again. Running brilliantly Left it another day and it won't start at all. It cranks but I have no spark. Has anyone got an answer for this. Ibe already swapped the crack sensor over. I'm hoping it's just a relay that was intermittently broken and now has completed given up. Any help with this is appreciated.

Cougar Posted August 4, 2016 Share Posted August 4, 2016 You may have an intermittent power connection. I suggest you check the power to the ignition system while the trouble is occurring. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted August 5, 2016 Share Posted August 5, 2016 possible crank position sensor. On some older cars - they can get intermittent. Link to comment Share on other sites More sharing options...
matt167 Posted August 5, 2016 Share Posted August 5, 2016 What engine control system are you running? I know theres a couple that the EJ20G can run including USDM EJ25D ECU if used with fuel enrichment Link to comment Share on other sites More sharing options...
gobby1sock Posted August 5, 2016 Author Share Posted August 5, 2016 Already changed the crank sensor It is using the standard V5 ECU. I'll have a look tonight and I'll check any possible connection issues. I may be a while Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted August 5, 2016 Share Posted August 5, 2016 could it now be flooded? Hold the gas pedal to the floor - that signals the ECU to use 'clear flood' mode and shut-off the injectors. Link to comment Share on other sites More sharing options...
gobby1sock Posted August 5, 2016 Author Share Posted August 5, 2016 Ok. I'll try that. It does have an after market fuel pump and pressure regulator set to 40psi so maybe it doesn't like that much. It just strange where it stopped working after I left it for a while Link to comment Share on other sites More sharing options...
gobby1sock Posted August 6, 2016 Author Share Posted August 6, 2016 I've had a look at the pickup. Tried the foot on the gas, not that. I've checked all work I've done recently an I can't find a fault. I plugged the diagnosis plugs together and my ignitor started clicking but of I disconnect the diagnosis plugs it doesn't make a noise. Any more ideas?

1 Lucky Texan Posted August 6, 2016 Share Posted August 6, 2016 hmmm....squirt some starting fluid into the intake and see if it fires? Link to comment Share on other sites More sharing options...
gobby1sock Posted August 6, 2016 Author Share Posted August 6, 2016 Tried that. No luck it stinks of fuel after cranking. So it's definitely getting fuel Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted August 7, 2016 Share Posted August 7, 2016 maybe slipped crank/cam timing? ECU might disable ignition if crank/cam sensors disagree? Link to comment Share on other sites More sharing options...
gobby1sock Posted August 7, 2016 Author Share Posted August 7, 2016 (edited) Looks like the timing is out. Mines a quad cam and the two marks on the cam gear on the left hand side of the car are out by 2/3 teeth Edited August 7, 2016 by gobby1sock Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted August 7, 2016 Share Posted August 7, 2016 how old/long since the timing system was serviced? details on engine, year, mileage, etc. the toothed idler, or the tensioner will often go bad before the belt breaks - even with 'time'. I seerviced that system on my 2006 WRX at just under 9 years of age, even though it had only about 60K miles on it - and the toothed idler was very loose and wobbling slightly, another idler was also very loose. The grease goes bad in them with time I guess. Low usage for a car is also considered 'sever duty' and that is why many items need to be serviced according to the TIME side of the maintenance schedule.

gobby1sock Posted August 7, 2016 Author Share Posted August 7, 2016 Don't know when it was last done. Bought the impreza just so I could do this conversion to my pickup. I'll get a timing kit and I'll do it soon. It better work afterward Link to comment Share on other sites More sharing options...
