Car wont start. Help!

The black throbber is sick again!

Took car to local garage to have steering issues resolved. Refurbish the power steering pump took longer than expected and when fitted 2 weeks later battery was discharged. Car was charged on trickle charger and then booster pack, but would not start. Garage do not know what the problem is, but have not checked for spark yet. Car turns over and smell of petrol is present, so does not appear to be immobiliser related. It has an HKS f con pro piggy back ecu. Anyone have any ideas. I have really lost the love. Every little problem causes me lots of heartache and I now feel that most garages now expect me to just take my pants down and bend over.

May not be enough fuel though you can smell it. Could either be ignition or fueling. Best to check for a spark, have you checked fuel pressure.

 

To be fair I would of thought those thigns most garages would of checked or at least suggest checking. Whats the voltage when it's starting, have you tried starting it with a jump pack on the battery

It's still at the garage and they have been a bit backward in coming forward if you get my drift. I turned up in darkness for a progress report to be told it wouldn't start. It went to them with £30 worth of fuel and shouldn't have gone far. The fuel pump did have rhythmic knocking noise to it that it didn't when it went in. The guy who has been working on it says he hasnt a clue when it comes to electronics. What the f do I do now? It started on the button first time every time when it went in and had only just been re mapped by Ryan g. I am gutted and really wouldn't give. T*ss if it went up in flames at the garage. £30k worth of my money and not worth a soapy t*t w*nk at he moment.

 

Rant over! That is all!

I just hope they know what they have done and fix it. I have had the car since 2006 and I haven't had it on the road running properly for more than a year in all! I am now just tired of trying to resolve problem after problem and spending more and more of my kids inheritance. I could have bought a well spec'd Ultima for what this car has cost!

As above, i'd look at the main fuse in the engine bay, then the igniter both are easily damaged if being jump started, failing that then maybe whip plugs out and clean them up, my supra flooded once and wouldn't start until the plugs were removed and dried out, never had an issue since.

I did this only 2 weeks ago.

 

Large 120AMP fuse and the Igniter Pack was fried for me. Replaced both and started immediately.

You will need to contact keron for a 120amp fuse and LittleNum has a couple of good Igniter packs for sale too at around £45 each.

Will the starter motor turn car over and run the fuel pump if the main fuse has gone. All seems to be working apart from not get that final spark. Alarm activates and de-activates. Car turns over. Just no bang!

From what you are saying I am favouring the igniter pack. Battery is new, alternator is reconned. Coil packs and clps are new. Where is the igniter thingy?

Crank sensor lying about when to fire the plug?

 

My monies on this, if they have replaced the steering rack they may well have knocked the connector off, or hit and moved the hall effect sensor (crank sensor) out of alignment with the star gear behind the crank pulley. Especially if it is true that they say you have spark, fuel and it turns over. Can only really be down to timing or no compression IMO.

Update to the non starter,

No change.

Still not starting.

Check list so far. Plugs are sparking. Fuel is getting to the cylinders. There is compression within the cylinders.

Mechanic says he has not seen a vacuum pipe that goes from the power steering via a switch to the throttle body before!

 

Any one got any ideas? Now been off the road for ov 3 weeks for a job that should have taken 1 hour!

Hire a lorry and bring it down with you when you come down. I'll make it run. ;)

I know, I only wanted the power steering pump changed nearby in case the rack had a problem. Should have been a simple job. Problem is the garage is my 'friendly' MOT place. Can get a trailer for £35 and shift it wherever probably SRD but Lee is so busy at he moment!

I would just go down and check all of the harness is plugged in properly there are a couple of plugs around the PS pump and it could be something really silly...

 

There is an engine on eBay with done decent close up pics of all angles of a TT engine if you want a simple visual reference....
