housebuilder Posted October 13, 2012 Share Posted October 13, 2012 Finished the wiring and decided to put some fuel in and give her a turn. I have a spark and after reversing the two wires on the fuel pump I have fuel being delivered to the fuel rail. The car wont start and I cannot smell any fuel in the pots with the plugs out. I have taken off the fuel rail and turned the engine over but nothing seems to be coming out of the injectors. Should I expect to see something? Any help or suggestions appreciated as always Quote Link to comment Share on other sites More sharing options...
Mark (smokey mow) Posted October 13, 2012 Share Posted October 13, 2012 Have you got the flow and return fuel connections to the rail the correct way round? The return fuel line is the one connected to the fuel pressure regulator. Quote Link to comment Share on other sites More sharing options...
jonjh1964 Posted October 13, 2012 Share Posted October 13, 2012 Have you plugged in a laptop to the Omex ECU and followed the initial setup for the TPS? Quote Link to comment Share on other sites More sharing options...

jonjh1964 Posted October 14, 2012 Share Posted October 14, 2012 S/W allows you to set the min and wide open throttle (WOT) position for your Throttle Position Sensor - essentially allows the ECU to understand your mechanical throttle set up. To be fair, I wouldn't have thought it would have effected start up as you would have pressed the accelerator but you will need to set it to get the idle etc set up - are you using the Ford single Throttle Body or the OMEX/Jenvey Individual TBs? Took me over a month to get the synchrometer working and balance the Jenvey TBs - but what a roar when I did!!! If you're running the S/W on Windows7 you'll have to make a folder and then use the configure on the MAP3000 S/W to point to it - I think my blog covered this in mid-ish Aug.

housebuilder Posted October 14, 2012 Author Share Posted October 14, 2012 Amatuer I am! To be fair it just looked like they were the right way round. When smokey mentioned the pressure relief valve (and I realised what that was!!) I realised that that was the return side Quote Link to comment Share on other sites More sharing options...

I realised that that was the return side I flattened my battery and spent ages trying to work this one having persuaded myself they were right !

markcoopers Posted October 16, 2012 Share Posted October 16, 2012 When we built a car on the Westfield stand at Stoneleigh back in 2006 i think, we did that as well......but with a few hubdred public looking on listening to the starter chattering away. Swapped the lines over and flick of the key Quote Link to comment Share on other sites More sharing options...
