DME & Fuel Pump relays

[Ohrammer]

HI there having a major issue with the 986 2003 2.7 Boxster
had a slight stutter when accelerating hard and was advised to change plugs and coils
Got the car up in the air wheels off and replaced the coils and spark plug used like for like replacements all part numbers the same Beru coils and Bosch spark plugs it was very fiddley but managed to get them changed. Al torqued up and done one cylinder at a time so no chance of getting the connectors wrong

the battery was off being charged, replaced the battery and the engine turns over at a good speed but does not fire up.

I have checked all the fuses in the foot well nothing blown, before i get her back up in the air and start rechecking my work i have been told it might be worth checking the DME relay and the fuel pump relay

i can see these (Just) above the fuses a set of relays but not sure which one is which or if these can be local part shop replacements or if i need to order from Porsche?

Here's 996 relays layout. Should be very much same and same locations (some at the footwell and some in trunk 986 / enginebay 996).

thanks for the information

Could i take a relay from say the flasher and put it in the fuel pump socket to test the relay?

question says you might be over your head. Get someone with some relay experience to remove the relay and jump the power to see if the relay is not working. Good Luck

So i have tested every relay in the car both in the trunk and footwell they are all good checked every fuse none have blown seems i need to get back under the car and check each bloody coil and plug

Not very happy and wish Santa had brought me a car lift and not a new set of torque wrenches

went through this ritual, after testing all the relays, my fuel, while pumping fuel, failed a pressure test.

I spent a lot of time before I figured this out
