I´m having lots of problems starting my 33 1.7 16V.
The car has been hibernating for a lot of years, because I broke the engine. After that I repaired the engine, but since then I´m having problems to turn it on.
Some times I go to the garage and crank it and it starts, other times it doesn´t start at all even if I try, and try, and try...
So now its the time to solve the problem so I can take it out for a drive...
What I have done/checked is:
- My car is NON-cat.
- Removed all gasoline (7 or 8 years old) and put 9 - 10 liters of 98 ron (yesterday)
- The fuel pump relay clicks and it has fuel on the injectors because when I crank I get the smell of gas.
- New rotor and new cap
- I have spark on the plugs (tested the HT leads with a plug)
- Fire order is correct, checked, rechecked... hundreds of times!
- Tested the engine temp sensor (the blue) for the injection and it gave 2500-2560 ohms at about 20º-23º (normal summer portuguese weather)
- Tested the crack sensor and I got about 600 ohms
- Sometimes I try to start it and it seams to start but nothing
- Sometimes it doesnt give any sinal of live, (like it doesn´t have gas or spark)
- If I could not start it, and I "invert" the HT leads 180º, it gives a loud bang.
- Sometimes it starts (rarelly), and when it starts it idles very bad.
- Sometimes when it starts I have to use the acelerator keep it on, and on some of that times it doesn´t go by 2000rpm even if I put my foot down. If I take my foot from the accelerator the engine stops. After that I can´t start it again.
- Last night noticed the spark is very weak!
Used 2 different spark plug leads, one from a normal carburated 33 (I know they are not compatible) and another one from the 33 16V, and also tested both leads with 2 different plugs, one 25HLD and a NGK from some car. With the lead from the carb 33 I had a very big and normal spark, with the 33 16v lead I got a very small and weak spark and sometimes (some turns) no spark.
So I think the problem could be on this...
I Know that the 16V HT leads are different and have some resistence.
If I measure the resistence with a tester what are the value I should get?
I measured one original from Alfa and it gave me about 6.5 K, measured another from Lucas and it gave me near 11K.
Should the small HT lead that connects the coil to the distribuctor cap also has high resistence like the other 4 HT leads or this one should have low (or no) resistence? What value should I get if tested?
