After not really touching the 205 for about 2 years I decided at the weekend that I'd have a crack at it.
After buying the Manta I've not really felt the need for a project but something was nagging away at me to do some work on it.
I bought a new battery, a compressor, an airgun, some impact sockets, a set of spark plug leads, a dizzy cap and headed down the garage.
Now since the engine went in I've not been able to get it to run well - but I've never really done any troubleshooting as such - just swapped various items and hoped for the best.
So this time I did it properly.
First off, fit the new battery.
Then, removed the injector rail and held it in the air whilst cranking the starter to check I was getting fuel to each cylinder. 4 nice constant jets told me that yes, I was.
Then I checked the coil was giving out a decent spark - yes, it was.
Engine started and ran, but very rough. Although that said, it's only fitted with a 4 branch manifold - no exhaust system. So I hooked up a temporary exhaust system made of bits of 205 and Manta to give me half a chance of hearing any misfires properly.
Replaced the injectors and did a compression test. Even across all 4 cylinders so not head gasket (unless the liners had dropped and all 4 had gone - unlikely as pressure was decent on each bore)
Check for spark - yes, sparks on 1, 2, 3 and 4.
Put it all back together - still missing like a ****
Tried swapping a few leads around, only made it worse.
With the engine running, pulled each lead in turn. Confirmed not firing on 1 and 2 but both were getting spark out of the block. Considered buying spark tester to see if output was sufficient.
Got annoyed, scratched head, consulted the old man.
If you eliminate the impossible (no spark, no fuel, no compression) then what remains, however improbable (firing order, unchanged from the donor engine and matching my tech diagrams) must be the truth.
So swapped plugs 1 and 2 on the dizzy cap and tried again.
BINGO
Mojo restored, tonight I stripped some bits off my replacement beam to clean them up and began to dismantle the one on the car currently (which is shagged)
God I love my compressor, I'd forgotton how much easier everything is with air tools when you are dealing with big, rusty nuts and bolts.
Updates and pics to follow, making the most of my renewed enthusiasm while it lasts
