  1. Thanks Brian. All wired up and it’s settled down nicely.
  2. I’ve changed the square brick plenum to a classic slopy top type and consequently now have a different stepper motor. I need to modify the wiring from the rectangular plug to a square plug but don’t know which wires go where! This is the current plug and wiring - the plug is marked A, B, C & D; And this is the socket on the classic type stepper motor I’ve now fitted; So the the question is which is A, B, C & D on this square socket? Thanks in advance for your help 😁
  3. GEMS. Looks like I’m sorted now anyway. Thanks.
  4. Which wires are which on the P38 V8 4.6 cam position sensor? I took 3 wires off - brown/orange, red/black and grey/blue but now I don’t know which is the +5v, signal or ground! The sensor side of the connector all wires are black. Thanks for your help.
  5. Which V8 models have the Slopey top plenum chamber like the photo? Any advice or part numbers gratefully received. 🤞
  6. That’s a very kind offer @FridgeFreezer, can I bank that for another day (another problem)? I’ve measured everything up and I’m happy that the flywheels as they are fitted are within 1mm of each other. i.e. the same. I think the problem may be with the starter but it was behaving itself when I did a bench test so I’ve cleaned it all up and put it back on. So far no problems. 🤞
  7. Are all flywheel dimensions the same and therefore interchangeable? I have a 4.6 gems engine that was originally mated to an automatic gearbox but I have swapped this for a manual flywheel for a LT77 box. I found a NOS manual flywheel and fitted it without too much thought but sometimes, only sometimes, the starter doesn’t engage properly and there is a terrible gnashing of teeth. (Mine and the flywheel!) The possibilities I have considered are; 1) The manual flywheel sits too far from the starter and the solenoid can’t throw the gear far enough and I may need a different starter? 2) My original starter and manual flywheel configuration are fine but the started is playing up and needs refurb or replacement? 3) The flywheel I bought wasn’t actually a P38 manual flywheel at all 😬? 4) I’m an idiot? 5) Any combination of the above. If you know what’s causing the problem or better still know the answer I’d love to hear from you. Thanks in advance.
  8. She runs! Thanks very much for your help @elbekko @Escape @Bowie69 @FridgeFreezer https://share.icloud.com/photos/08FI85Fg2KSlXJLLxUNWLBnLg#Eastleigh_-_Fair_Oak

  10. Sounds like we are going for a similar set up @Escape. I’ve got a manual flywheel now so I can continue to use my LT77 box and have removed the spacer as you suggested from the cps and see good rpm when cranking the engine. I’ll post some photos tonight. 😁
  11. That’s good news @Bowie69. Great advice @Escape and I’ve found a sensor for a manual 😁. The engine is in an Opel Manta and being managed by a stand alone Emerald ecu. I don’t know the full history of the engine but RPI told me that their records show the engine was built in 2001.
  12. Thanks guys. So it won’t damage the ecu if I connect them up the wrong way round? I thought it would send the opposite message 1:36 not 36:1 🤷‍♂️ Also are there different cps’s for manual and automatic. I’ve changed the flywheel and the sensor seems to be too far away from the trigger wheel. If they are different does any one have a part number for the manual one? Thanks.
  13. It’s a 2001 Gems engine built by RPI Engineering. Thanks for your help @elbekko.
  14. Can anyone tell me which is the signal wire on a P38 4.6? I have two wires to choose from Pink & Black or Black & Yellow. Thanks in advance for your assistance. 👍
