timandchris Posted July 21, 2006 Posted July 21, 2006 Tried our first start this evening. No reading on oil pressure guage. Although the engine turns over well enough and most of the lights and things work no hint of firing from the zetec. Suggestions welcome, but a particular question about the fuel pump - when we switch to second position we can't hear the fuel pump 'whirring' would we expect to? This is a bog standard westfield 1800 Zetec... Tim and Chris Quote
perksy Posted July 21, 2006 Posted July 21, 2006 You should hear the fuel pump prime Check Fuse, Wiring & Inertia switch Are you using Carb's or Throttle bodies though Quote
fordy Posted July 21, 2006 Posted July 21, 2006 If its running injection, the fuel pump may only run when its getting a signal from the crank sensor - i.e when its turning - if the fuel pump doesnt fire up when your cranking it,, then thats probably not the setup you have - unless its broken. Quote
timandchris Posted July 21, 2006 Author Posted July 21, 2006 OK, nobody laugh but even having spent months building this we don't really know what a Throttle body is!!!! Does that win us some kind of cretin prize. Anyway it must be TBs as it def has no carbs. Engine turning over is sufficiently noisy to mask any noise made by fuel pump. Quote
Peter M Posted July 21, 2006 Posted July 21, 2006 The fuel pump as perksy says should prime for a few seconds on ignition switch on.On first trying to start my standard 1800 zetec had a similar problem with fuel pump not working after numerous checking of the obvious inertia switch/fuses etc still could not get the pump to run ,on speaking to mark at the factory was told i needed to swop 2 wires over on a 4 pin plug in engine bay,this may be the same in your case. As to no oil pressure try cranking engine with plugs removed also may need to prime oil filter with some oil. Quote
Peter M Posted July 21, 2006 Posted July 21, 2006 Anyway it must be TBs as it def has no carbs. Just looked at your build site of your engine ,you have the standard westfield single throttle body set up. The engine does not need to turn for the fuel pump to prime just ign on then it should run for about 2 seconds then goes off.Once engine runs then the pump is on all the time. Quote
timandchris Posted July 21, 2006 Author Posted July 21, 2006 OK thanks everyone...the inertia/cut-out switch is depressed which I believe is correct for running, so we'll have a beer now and think about debugging in the morning! Quote
perksy Posted July 21, 2006 Posted July 21, 2006 so we'll have a beer now and think about debugging in the morning! Man after me own heart All will be clear in the morning after a few bottles of Stella Artois Quote
pgh Posted July 21, 2006 Posted July 21, 2006 You have got the immobiliser jumper/loop connected haven't you? Not having that will stop the fuel pump from powering up. Try the Schrader valve on the fuel line too after turning the ignition on - you should get a small hiss of pressure out of this if the pump has been doing its job. Quote
richardzetec Posted July 22, 2006 Posted July 22, 2006 If you have a spark and the pump runs as stated for a second or 2 when you switch on, my problem was stuck injectors, I'm also running with same Westfield plenum chamber, engine was stood aroud for about 9 months. Richard Quote
nikpro Posted July 22, 2006 Posted July 22, 2006 I had exactly the same problem and it turned out to be a faulty fuel pump relay; there are two relays near the ECU - try swapping them with ones that you know are fine; if you can't hear the fuel pump running the engine will never start. As said previously the pump will run for a short time when the ignition is switched on to prime the fuel system. Quote
NRW Posted July 22, 2006 Posted July 22, 2006 Check pump wiring. As it will quite happily run the wrong way also not that easy to hear (mine wasn't) only briefly runs to prime system initially If you prod the Schrader valve with a small screwdriver (this is on the injector assembly looks like a bicycle tyre valve). Fuel will P**S out if everything is working ok. So have a rag ready!!! may just take a lot more cranking than you think! Also on the oil pressure and other instruments the wiring to each instrument will need swapping over this is in the manuel goiod luck Quote
SteveC Posted July 22, 2006 Posted July 22, 2006 Tim and Chris, send me a pm with where you are in Oxford and I'll see if I can come round and help out, not making any promises for a magical cure, but you never know! Especially as i know nought about Zetecs Steve Quote
Al Yupright Posted July 23, 2006 Posted July 23, 2006 I'll echo the comment about speaking to Mark Walker at Westfield. I build a "Madness" Zetec kit for someone a few years ago and that wouldnt start. Turned out to be the main engine loom connector was wired incorrectly and needed two wires swapping over. Very frustrating! It is apparently a common problem on a batch of looms. Quote
timandchris Posted July 23, 2006 Author Posted July 23, 2006 Thanks again all. Yes I have spoken to Mark, He suggested putting a meter across the fuel pump terminals. But I have had to go away for a few days and Chrissy is starting driving lessons so probably won't get a look until next weekend. Now someone mentioned immobiliser. We have a spare loom connector marked immobiliser and have done nothing with it...please tell all. (Private message sent to SteveC) Quote
